The Stillwater Girls by Minka Kent

In the isolated woods of Stillwater Hills, nineteen-year-old Wren and her sister have waited sixty-three days for their mother to return. She left with their youngest sibling, promising to get help—but never came back. As winter deepens and supplies dwindle, a mysterious stranger appears at their door, forcing the sisters to question everything they've ever known about their secluded life.

Desperate and afraid, they flee into the unknown, leaving behind the only home they've ever known. When they stumble upon a house at the edge of the forest, they find themselves drawn into a world they never knew existed—one filled with comforts they've never imagined, but also with questions that become increasingly difficult to answer.

As the sisters begin to unravel the truth about their isolated upbringing, they discover that some secrets are better left in the woods. In Stillwater Hills, every family holds mysteries—and some will do anything to keep them hidden.
