Wildwood dancing - Juliet Marillier

The wildwood holds many mysteries. Jena and her sisters share the biggest of all, a fantastic secret that enables them to escape the confines of their everyday life in rural Transylvania. They have kept it hidden for nine long years.

When their father falls ill and must leave their forest home over the winter, Jena and her older sister Tati are left in charge. All goes well until a tragic accident allows their overbearing cousin Cezar to take control. The appearance of a mysterious young man in a black coat divides sister from sister, and suddenly Jena finds herself fighting to save all she holds dear. With her constant companion, Gogu, by her side, she must venture to realms dark and perilous in her quest to preserve, not just those she loves, but her own independence as well.
