It's that time of year again-when I attempt to read all of the Whitney finalists: http://whitneyawards.com/wordpress/2014/01/31/2013-finalists/
9. Jennifer Shaw Wolf's Dead Girls Don't Lie is a YA finalist for the Whitney awards.
Jaycee's summer has gone unexpectedly awry. Her best friend, Rachel, is dead--murdered. And Jaycee is torn by guilt, for not being there for Rachel the night she died (she deliberately ignored her texts to spend time with a boy at a party). But after receiving a strange video from Rachel, Jaycee starts to investigate Rachel's death. And the more questions she asks, the more questions she finds. Jaycee isn't sure who to trust, but if she can't figure it out, she might be targeted by the same people who targeted Rachel.
I enjoyed this one--it was cleanly written and the tension builds nicely. If I was frustrated with Jaycee because of her insistence on keeping secrets (rather than enlisting the help she desperately needs), I also realize there might not have been as much of a story.
