They All Had a Reason Publisher's Summary
Sixteen-year-old Charlotte is convinced her life would be perfect if she could only get past the one obstacle holding her back: a girl named Bellany Silverfield, who seems to have it all - beauty, popularity, power, and the boy of Charlotte’s dreams. But when Bellany is murdered, Charlotte’s life doesn't get any better. In fact, it gets much worse. Charlotte worries that circumstantial evidence and rumors of motive will make her a prime suspect. She's forced to question the loyalty of her closest friends and to place her trust in a boy she barely knows. But one of these people is definitely lying to her.
