The Deadly Sister — Eliot Schrefer

From the author of The School for Dangerous Girls, a suspenseful stunner about loyalty, sibling rivalry, and murder.

Abby Goodwin is sure her sister Maya isn't a murderer. But her parents don't agree. Her friends don't agree. And the cops definitely don't agree. Maya is a drop-out, a stoner, a girl who's obsessed with her tutor, Jefferson Andrews...until he ends up dead. Maya runs away, and leaves Abby following the trail of clues. Each piece of evidence points to Maya, but it also appears that Jefferson had secrets of his own. And enemies. Like his brother, who Abby becomes involved with...until he falls under suspicion.

Is Abby getting closer to finding the true murderer? Or is someone leading her down a twisted false path?
