The Souls of Lost Lake By Jaime Jo Wright

Wren Blythe has long enjoyed being among the Northwoods, helping her father with programming at a youth camp. But when a little girl in the area goes missing, an all-out search ensues, reviving the decades-old campfire story of Ava Coons, the murderess, who still roams the woods. Joining the search, Wren stumbles upon the Coons cabin ruins and a rotting porcelain doll. But even more terrifying is seeing her name etched on the doll’s foot like a sinister omen.

In 1930, Ava Coons has spent the last ten years carrying the mantle of mystery since she emerged from the forest as an eight-year-old girl, spattered with blood, dragging a logger’s axe. She has accepted she’ll never remember what happened to her family. When a member of the town of Tempter’s Creek is murdered, rumors spread that Ava’s secret is more malicious than previously imagined.

Both women discover that to save the innocent, they must face an insidious evil.
