Stay on the roads. Don’t enter the woods. Never go out at night.
Those are the rules in Rowan’s Glen, a remote farming community in the Missouri Ozarks where Ivy Templeton’s family has lived for centuries. It’s an old-fashioned way of life, full of superstition and traditions, and sixteen-year-old Ivy loves it. The other kids at school may think the Glen kids are weird, but Ivy doesn’t care—she has her cousin Heather as her best friend. The two girls share everything with each other—or so Ivy thinks. When Heather goes missing after a May Day celebration, Ivy discovers that both her best friend and her beloved hometown are as full of secrets as the woods that surround them.
