The Wood by Chelsea Bobulski
When Winter's dad goes missing during his nightly patrol of the wood, it falls to her to patrol the time portals and protect the travelers who slip through them. Winter can't help but think there's more to her dad's disappearance than she's being told. She soon finds a young man traveling in the wood named Henry who knows more than he should. He believes if they can work together to find his missing parents, they could discover the truth about Winter's dad. The wood is poisoned, changing into something sinister - torturing travelers lost in it. Winter must put her trust in Henry in order to find the truth and those they've lost. Bobulski's eerie debut is filled with friendship, family, and the responsibilities we choose and those we do not.
