A bit more adult than her Vampire Academy or Bloodlines series, I'll admit that I was a bit apprehensive coming into this series (I cannot stand the Bloodlines series and the Dark Swan series had me in fits of annoyance). Luckily, Succubus Blues was actually better than I'd imagined (although VA still remains my favorite Richelle Mead series so far). 
 Georgina is actually interesting and entertaining (definitely more Rose than Sydney, thank god), although she has the same terrible taste in men that Rose does. She's a succubus, doomed to steal the energy of men through sex for the rest of her life because she sold her soul (more on that later). Sometimes the "Georgina is so hot" routine gets a little old, but at least it's justified; when a succubus steals energy, they get this glow that attracts humans to them and basically turns them into drooling weirdos. This actually gets amusing, like when she's screwing up coffee orders and when the customer comes back to bitch, she flashes a smile and they forget all out it and walk away whistling. For someone who has lived a long time she can get pretty dense and teenagerish, but that seems pretty par for the course in most of Ms. Mead's novels. (Rose has an excuse, being a teenager, but Eugenie does not.) 
 I'm not sure why Ms. Mead opted to have two of Georgina's friends be vampires instead of other immortal types (vampires are super yawn-worthy in the Succubus series), but sure, why not? They're not really there for any specific purpose other than to show Georgina has friends (all male, at that), to tease her and remind her how hot she is. (Okay, I'll admit I don't remember their names and just had to go look them up; Peter and Cody. Shows just how unmemorable these guys are.) There's also an imp named Hugh... and I pretty much just remember his name and that's it. This bunch of immortal misfits don't usually do anything interesting except hang out, go to Georgina's ridiculous dance classes, and bar hop? I dunno, they're really just kind of there. Basically, they pad the character numbers. Yawn. Georgina's archdemon boss, Jerome, and his best bud Carter, who's an angel, are a bit more interesting and actually involved in the plot, but still fall under 'background noise', unfortunately. (I love Carter, guy's so weird and awesome, definitely my favorite character thus far.) 
 So, a long time ago, in a galaxy far, far away, Georgina was actually a mortal named Letha. She got married to some boring ass guy and cheated on him with some dude who was way more interesting but got caught. Naturally, she loved her boring husband more and was so upset that she sold her soul to make him forget all about her. This led to her becoming a succubus and being forced to steal mortal men's energy, both to corrupt them and to survive. At the current time, Georgina is sick and tired of using good people so she only shags lowlifes much to Jerome's annoyance but since she's basically his favorite he lets it slide. When she's not hanging out with her friends, she's working at a bookstore/cafe and drinking white chocolate mochas like they were water. Oh, she's also screwing her boss, Warren, for a quick energy boost once in a while, because he's just a jerk who cheats on his wife so she feels zero shame in doing it. Basically she's a normal human being in the customer service industry, except she's a succubus. ;) 
 Other than the love story, the main plot of Succubus Blues is that someone is killing immortals. Worse, they all seem to be immortals that having been giving Georgina grief lately. Jerome and Carter warn her to stay out of it, but she decides to ignore it and plays Nancy Drew anyway. From vampire hunters to Carter to a few other theories, Georgina finally finds out that the killer is a nephilim; half angel/demon, half human. She has zero idea who it is, but the nephilim is very interested in her because they keep sending her notes, letting her know they're watching her progress (and watching her have sex with Warren, lol). Georgina does get attacked, but Carter saves her and acts as her bodyguard for a time in between trying to find the nephilim when their energy signature shows up. Eventually the nephilim finds Jerome's apartment and ransacks it, leaving a warning. Georgina figures out that the nephilim is Jerome's kid, but it's a moot point because the archdemon really doesn't give a damn and will smite the little bastard if he has to. Ouch, cold. Thinking the nephilim is after Jerome, Carter decides to guard him instead, freeing up Georgina to drink mochas in private, or something. Later Georgina gets a note saying that she'd better protect her boyfriend or else the nephilim will kill him. But gee, Georgina doesn't have a boyfriend, so who is the note referring to? There are just so many men to choose from! 
 First, Warren. Sure, all she does is have sex with him on occasion, but better safe than sorry, right? Warren's your typical jerk; cheats on his wife with younger women and thinks Georgina's hot. He's not really around for much except to give Georgina an energy fix when she needs it and reminding us that he owns the bookstore. 
 Next, we have Doug. He's an assistant manager at the bookstore like Georgina. Human, sings in a band, flirts with Georgina all the time and like 90% of the characters in this book, just kind of there. He's not really memorable and just another reminder that human guys find Georgina hot. 
 Next is Roman. Georgina randomly choose him as her date when trying to get away from Warren's sexual advances early in the novel and he sticks around, determined to get to know her better. He's gorgeous, witty, very amusing and it's a shame Georgina keeps pushing him away when she's really into him (as we're reminded quite a few times throughout the book). Ah, Roman; he's so sweet and considerate to Georgina but she doesn't like falling for nice guys because she doesn't want to steal their lives away when they get freaky. Despite that, she invites him over to her house to help her put up shelves for her books and he's so inept at it I can't help but laugh at how endearing it is. The dates they finally go on are cute too; most of their scenes are like that and I just wanted to smack some sense into her every time she did a 180 and shut him down. Sigh. 
 Finally, there's Seth. Currently Georgina's favorite author who has just moved to town and writes his upcoming bestsellers at the bookstore she works at. And, well... Seth is as boring as a houseplant. Supposedly he really shines in his writing; it's where all his personality and expression comes through and yes, I'll agree, because damn this guy is dull. He's socially awkward and quiet, which is fine because lots of people are, but the characters insist on dragging him out with them where he sits in silence as everyone else has a good time because he doesn't drink anything except water and caffeine-free tea. I only know his name because he's in the book so often and for the life of me I can't remember what he looks like. Other than his supposed god-like writing skills, the only thing I remember standing out about him is his crazy t-shirt collection. Therefore, every time he is in a scene, all I can picture is Comic Book Guy from the Simpsons in a random t-shirt, I'm dead serious. That makes it hard for me to believe that Georgina is so hot and bothered for him, because I can't even remember his hair or eye color. Supposedly she's completely captivated by him because the girl has a thing for the artistic types (her husband when she was mortal was a musician), and... I don't know? Maybe she's in love with the idea of what she thinks he is because of how he writes? Maybe it's because he brings her around to his brother's house and she loves the family setting? (On that note, seriously, who drags a hung-over chick he barely knows to a birthday party for his niece when she's dressed like she's on a hot date? Seth, are you an idiot?) If he wasn't constantly shoved in my face throughout the novel, I'd probably forget him like I do... those vampire guys, whatever their names are. 
 So, who's the winner? Who's our nephilim? The answer is... Roman. (Of course, I actually liked Roman, he just had to be the bad guy.) Every hundred years or so, Roman gets pissed off at the status quo of heaven versus hell and decides to cut some bitches as a way to rebel. (Nephilim are hunted and killed by angels just for being what they are, ouch.) Despite all this, Georgina has wild sex with him, deluding herself into thinking it's to stall for time. Afterwards she does call for help discreetly, but of course, Roman is like "Hey, I'll give up my immortal killing ways just for you because I love you so much". Aw, it would be nice, but Seth comes and spoils it all, stupid Seth. Of course, Georgina isn't blameless either since she did call for help. Regardless, Roman's sister (Helena, who we see in the book several times as a New Age spouting nutter) is dead and Seth is exposed to the immortal world. Whoops. 
 The ending winds down with Georgina cutting a deal with Jerome; if he doesn't erase Seth's memories, she'll start having sex with good people instead of assholes and score some points with hell. She also spills everything to Seth, who dismisses her, but later gives her the book she asked him to sign way back near the start of the novel and basically says "Hey, I get that you're a creature of hell, but let's have a relationship anyway!" Yeah, that's not going to end well. 
 Overall, I really liked this book despite so many bleh characters. Georgina both amuses and frustrates me, just like Rose in Vampire Academy, but overall I love that she has flaws and is still wildly entertaining to me. Of course, I'm disappointed that Roman ended up being the 'bad guy' and Seth was the 'true love' because honestly, after reading all Ms. Mead's other series, I'm tired of the boring guy hooking up with our badass heroine (or in Bloodlines case, our witty, sexy vampire hooking up with a boring, so-called heroine, but if you want to hear my rant on that, check out all my Bloodlines series reviews ;) ), because 'opposites attract.' Seth is just there; he's basically a piece of furniture as far as I'm concerned. Sure, Georgina feels giddy while reading his emails because he's more expressive in them, but she and Roman actually clicked and had fun together. Romance aside, I liked Georgina's investigating, which was way more entertaining to read than her dance lessons, plus all the character interaction. This is a novel where I don't care that there's not much "ZOMG ACTION' because the plot flows and is engaging, not boring. Definitely will be reading the next book. 
 PS. Carter is up to something, and I hope it's a good something because I love that guy. There needs to be more Carter. His scenes with Georgina while he played bodyguard were cute, and really, daffodils? He's so weird and adorable. Seriously, some of his banter with Georgina is pure gold. 
 Carter brought me daffodils the next morning. I had no idea where he could have found them this time of year. He'd probably teleported to another continent. 
 "What are these?" I demanded. "You aren't coming on to me after all, are you?" 
 "I'd bring roses for that." 
 "Are you going to tattle on me now, Georgina? And here I thought we were making such progress. Perhaps we should have drawn out the small talk a bit more. You could have asked me if the weather would change soon, I might have commented how pretty you looked today, etc., etc. You know how it goes." 
 "How pretty am I then?" My voice caught slightly. "Pretty enough to fall for?" 
 The angel's lips twitched. "I knew you were coming on to me." 
 Yep, love him. :)
