Girls Who Play Dead - Joelle Wellington

When Mikky Graves left his small, stifling hometown of Prophets Lake to live with his estranged mother, he thought nothing could ever make him return for good.

Until his sister Kyla's best friend, Erin, is murdered.

Mikky never worried about leaving Kyla behind at their family-owned funeral home so long as she had Erin. But when Mikky heads home, determined to help Kyla grieve, the sister he encounters barely resembles the one he remembers. Mikky decides, then and there, to do the one thing that seems even more impossible than returning: stay.

As Kyla spirals further into her rage and secrets, Mikky realizes the only thing that can help his sister is finding the truth about who killed Erin. But the more he investigates, the further he's pulled into other ugly mysteries of Prophets Lake and the beauty brand that is its lifeblood. The town's rot runs deep, and everyone has something to hide. Perhaps no one more than Kyla herself.
