If you waltzed into Midnight's Daughter expecting a tougher Cassie Palmer (more along the lines of Kate Daniels and Anita Blake), be prepared to be sorely disappointed. I read the first two Cassie books and they're somewhat passable. Dorina's first book is a wreck. 
 Dorina is a dhampir, half-human, half-vampire. They're rare and shunned, but because her daddy is Mircea, she's supposed to kinda sorta get a pass? (And if the relationship between Mircea and Cassie didn't squick you out enough, Dorina is his six hundred year old daughter. I know, vampires, but holy uncomfortable, Batman!) 
 Anyway, most of this book, thankfully, is not sitting in a total of two rooms talking. However, the action scenes are marred by two things. One, Dorina is prone to "fits", where she blacks out and goes into a rage. This bypasses the fights entirely so that Chance doesn't have to write them. Two, for most of the book, Dorina is injured and can't fight properly, leaving the work to Louis-Cesare and other characters, so all we get are her observations. 
 So Dracula is on the loose because... I don't know, is it mentioned in Cassie #3, Embrace the Night? Because I didn't bother after the first two. Or maybe it was mentioned previous, I just don't remember because nothing really stuck for me in that series. Anywho, Mircea thinks that Dorina and Louis-Cesare can recapture Dracula because they're family. Right, sure. From there, it's one blunder after another, complete with Fey shenanigans because there needs to be some other subplot going on, I guess, and evil mages because why not? 
 I was hoping Dorina would be a tougher Cassie, but she's just like a small dog: all bark and no bite. She talks smack and gets smacked around. I don't know how she survived for so long (most dhampirs apparently don't) because she sometimes borders on TSTL. Louis-Cesare, I will never take seriously because of that ridiculous name and this book doesn't help. The whole time he's with Dorina he's thinking with his other brain because... I have no idea why. Reasons. It also doesn't help that he's constantly referred to as Radu's kid (even though I don't think he is? Was he just turned by him in the alternate timeline?), and Dorina is Radu's niece, so they're basically kissing cousins (or not. Whatever, I don't care). Radu was probably the best part of this book because I enjoy eccentric characters. 
 There isn't time travel in this book like there is in the Cassie Palmer books, which is great because Chance flubs up time travel theory a lot (Radu casually dropping timeline changes like it's the weather is just weird), and I generally dislike time travel stories. Instead of that, we get two other things I hate: dreams and flashbacks. Both are lazy story-telling and we're treated to at least... five of them, I think. It's one thing if someone remembers the past, it's another when we're flung into a flashback sequence that takes up four pages. Dreams are usually a lame way to move the plot forward. Also, Dorina ends up reading Louis-Cesare's mind a lot thanks to Fey wine, which is really cringy when he's going down on her later in the book. There's another thing I despise: mind reading. 
 In the end, Dracula is defeated by a side character, Louis-Cesare runs away, Dorina goes home, and the adventure is over. It's so... bleeeeeeeeeeeh. Unless you're really into the Cassie Palmer world, skip this.
