Allow me to start by saying, I loved this book. Well, not exactly loved... okay. Let me start again. I loved the subject matter. I was less impressed with the rest of it. 
 Cath and Wren (say it together; it's only mentioned once in the book but it made me chuckle anyway), twin sisters, are embarking on a grand journey called... college. Like most twins, Cath and Wren are polar opposites. Cath likes to stay in, Wren likes to stay out. And once upon a time, they were both obsessed with a certain boy wizard who had an awesome book series and faithful movies. Oh, you said Harry Potter? Harry Potter who? We're talking Simon Snow here, people! 
 Anyway. Cath is starting college, she's still obsessed with Simon Snow and is a popular fanfiction writer who's trying to finish THE ONE before the final book arrives. As someone previously in those shoes, I can't even say how much I felt Cath's struggle. It was huge nostalgia for me. I loved it. I hated it. I saw myself in Cath and I loved/hated it. 
 So while Cath is trying to handle writing fanfiction and school work (she takes a fiction writing class that she can't seem to stand), Wren is out partying it up because "I'm eighteen, this is college, I can do what I want" and I wanted to bring down the power on her because, hello, you're eighteen! Shut up, sit down, and do your school work--don't waste this opportunity! You can party when you're older! Yes, Wren's character really bothered me because she was snippy and insensitive to Cath--until something major happens. But let's not spoil anything. 
 I was pleasantly surprised that their dad, Art, had a presence throughout the book. At one point he does pull the parental strings and tries to rein in his daughters. But as is described, he struggles with a mental illness and Cath worries constantly for him, making life that much more difficult. She's stressed about school, she's stressed about her sister, she's stressed about her fanfic, she's stressed about her dad. Later on, he gets help when he realizes how his happiness is tied to his daughters' happiness; they all want each other to be happy. The family love was spectacular. 
 Let's talk Levi. I don't like Levi. Let's not talk about him--no, okay, we will. 
 I didn't find him to be a suitable love interest. I didn't find the other boy (WHY ARE THERE ALWAYS TWO BOYS??) to be a suitable love interest, but thankfully that never took flight. When we first meet Levi, he calls Cath "Cather" and even when she corrects him ("It's just Cath"), he insists on calling her Cather. I hated it. Every time my eyes saw Cather, my brain said Catheter. Also, if a girl asks you to stop calling her something stupid, stop it--it's not charming and endearing, it's annoying. Levi was the typical "older" playboy who didn't realize he could "love" until he met Cath. And when she figures out she has feelings for him, the book took the usual YA novel downfall. Cath forgot her main goal. She just wanted to bone Levi. Levi, Levi, Levi. 
 Okay, it's cool that you're infatuated and all, but let's stick to the program here. You're failing your fiction writing, you haven't finished your fanfic, and you're still freaking out about touching him. If you're freaking out about touching someone, you're not ready. Trust me, I know--I had the same feelings, we all do. Levi, however, seemingly pushes at these limits little by little to "break her out of her shell." Ugh. I could go on all day about how I don't like him. 
 Throughout the chapter breaks, we're given snippets of the Simon Snow novels and Cath's fanfiction. It's a neat little touch, because we're not just learning about Cath, we're learning about Simon too. I started to wish his books were real (and then gazed lovingly at my Harry Potter collection). We do, however, get some closure with Simon. When the final book is released, we're there with Cath and Wren, who have gotten over their major fights, and get to see a little bit of Simon's outcome. 
 All in all, it was a nice read. A little longer than it should have been, maybe. Although there were conflicts, it didn't feel like there was a conflict that anyone really grew from, so that slowed the pace and made it somewhat boring. The writing style worked for this subject. There were times, though, when the single word conversations got on my nerves. At least the dialogue is believable... annoying, but believable. Some YA novels struggle with that aspect and make their characters sound too young or too old; Rowell found a good mix. 
 I will say that if you decide to read this one, be very careful. If you used to be an avid reader/writer of fanfic, something about this book will spark that old wick and burn you up. Props to Rowell.
