Overall, I'd give this a 4.5, but I've bumped it up to 5 for Goodreads. I love this modern take on vampires. The lore and world building is well done, and the magic system is interesting. Love the theme of mystery that runs throughout as Rose tries to figure out what's going on with Lissa. Best modern vampire book I've read for ages. However I deduct half a point because some of the teeny high school stuff was a bit irritating at times. But I shall definitely read book two at some point.
