Lock Every Door

This is the third book I read by Sager, and idk about y'all, but having a protagonist whose main personality trait is having TrAuMa! and a almost love interest turn out to be (or a suspect of being) the Bad Guy didn't work the first time, or the second time, nor the third time!

I also think that the possibilities of what's going on are ultimately always more frightening to me than the actual twists and reveals.
