Just finished Uncovering Sadie's Secrets by Libby Sternberg. It's a mystery. In fact it was a finalist for the Edgar Award for Best YA Mystery a few years ago. If you're looking for a heavy duty, blood and guts, type of mystery, this isn't for you. It's what I refer to as a light mystery. The narrator is a teen named Bianca who is a high school sophomore. She starts to notice some strange things about a new girl in school and sets out to figure out what is going on, and to help the other girl out if needed. What I liked about the book was that the story was believable. The situations weren't completely outlandish like you see in some teen books. It also read pretty much like a teenager talking to you. It moved quickly and had enough hints and twists to keep you trying to figure out what was going on. It's also the first in a series, so if you like this one, you might want to check out Finding the Forger as well. Enjoy!
