Two Can Keep a Secret

Serviceable murder thriller, not as twisty as her first book. The payoff didn't feel very earned, but think teens will like this. As a side note, I'm SO OVER the stereotype of 80 year old librarians falling asleep on the job so that a character can come in to a (public, in this case) library to look at a book in secret. It's lazy and hackneyed writing and just dumb at this point in YA.
