Come Back Witch

A vacation from his university sounded nice until it ended with Vinces stranded in a mysterious forest. And when it couldn't get any worse monsters of his darkest nightmares were inhabiting it. Mirrors steal souls, goblins demand impossible choices, and every creature obeys ancient rules that must be understood before they can be survived. Guided by a mysterious silver-haired woman who may be a witch—or something far worse—Vinces must uncover who is at fault for those changes and how he can survive them. — Description from novelcodex.org
