Estival

Sky is fifteen when an ordinary outing through a park turns into a crossing into another world, and then another, and then yet another. Her only goal is to find her way back home, and getting there means forming unlikely alliances, fighting monsters that can change their shape, and learning to use powers she has only just discovered.

Sky has lived between two cultures for her whole life, and she brings a stubborn streak of humor and a lively spirit to every new place. Each landscape she passes through is different, and she must work out who can be trusted and who is working against her. The villains she meets seem to have trouble coming up with names that suit them.

This is the first book in the Seasons of Fore series. The journey begins here, and further volumes are on the way.
