For a summer read, this was fun and frivolous. I'm actually quite disappointed there are two more books, because YA is really lacking in light standalones and this could have been wrapped up in a book. Especially with it's silly and irreverent tone. Everything that tied into a sequel for this actually were the parts my eyes glazed over for. 
 I also feel like any Buffy fans will have already seen so much of this book, but since i never watched that much I was able to have more fun with the teen girls chosen one tropes, even though I have also seen them a million times before. 
 I enjoyed the couple for the most part, despite a few key fights between them actually crossing a few lines. I know it was a vehicle to get her to try and slap him to prove she couldn't hurt him, but I found the male love interest did not exactly redeem his previous acts against her as her mortal enemy in high school (publishing personal secrets in a student newspaper doesn't make him Edward Snowden. He's just an asshole). Because of this, I found if her was even a shade more despicable, this series would have been marketed as her personal hell and in no way romantic. There needs to be a bit more wiggle room between villain and boyfriend. 
 So while a totally fun and harmless summer read, I could stand more diversity. Honestly containing this to one book would have been for the best, because there's a weight to trilogies and this just didn't have enough substance to span several books. It's unnecessary to give this two more books, I would have loved for this one to have a bit more work put into it instead. Wasted effort really. 
 But all in all I enjoyed the read and had some solid laughs. It was cute, when not requiring thought.
