For months, Summer is trapped in a basement with three other girls―and the man who took them. They are his flowers. But flowers can't survive long cut off from the sun, and time is running out in The Cellar. Then in The Cabin, a weekend of partying is just what Mackenzie needs, but when two of her friends are murdered…she realized she could be next. When a strange love note arrives for Lylah's friend, they all laugh it off. But when that friend never comes home, a new note arrives: Your turn. Love is about to turn deadly in You Will Be Mine.
