There's Someone Inside Your House by Stephanie Perkins

One-by-one, the students of Osborne High are dying in a series of gruesome murders, each with increasing and grotesque flair. As the terror grows closer and the hunt intensifies for the killer, the dark secrets among them must finally be confronted.

International bestselling author Stephanie Perkins returns with a fresh take on the classic teen slasher story that’s fun, quick-witted, and completely impossible to put down. 

I have to say I only picked this up because I really like Perkins' writing style and characters. Obviously it's very different from her other books and I'm not sure it quite hit the mark. I liked it, it's not my usual genre, but even I could tell it was standard high school slasher. Oh, and I do have to mention definite trigger warnings for gore, as well as severe hazing/mentions of suicide. 

Makani was a decent protagonist - her Hawaiian culture was very important to her and very obviously out of place in her new home. She had been shipped over by divorcing parents to her grandmother's, partly so she wasn't involved in the separation and partly so she could have a new start after some horrible incident at her old school. This was mentioned a lot and left me speculating more and more bizarre things that could have happened, but when it was finally revealed - yes it was horrific - it was a little bit of a let down. Her love interest, Olly, was the typical tortured, shy goth boy but he got some very good development and he really was quite sweet. 

Overall I liked it, but didn't always feel like a horror story - the crimes were gruesome and there was, for the most part, that sense of someone looking over your shoulder. But it was also very character driven and a surprising amount of romance - which I like in a story but I can understand why others didn't appreciate it.
