A new shapeshifter school is opening its doors. At Redcliff High, everything revolves around the creatures of the sky! Young wolf shifter Sierra is eagerly anticipating the opening of Redcliff High: her parents' new shapeshifter boarding school on the rocky coast of California. Will her classmates be nice? And what animal forms are hidden within them? Sierra quickly befriends wild horse girl Amy and tiger shifter Summer. However, a group of bird shifters calling themselves the Windwalkers excludes anyone who cannot fly. Sierra would love to get to know their leader, the proud golden eagle Sky, better. Meanwhile, strange incidents are piling up in the area around the school. Rare animals are disappearing, and mysterious bones are being discovered elsewhere. Sierra's instincts are awakened. Can she find out who is behind all this – and whether the shapeshifters at Redcliff High are in danger too? But then Sierra suddenly feels a new animal form awakening within her – and this animal is definitely not a wolf... Here comes the new major shapeshifter series by Katja Brandis, the bestselling author of Woodwalkers and Seawalkers! Thrilling flying scenes, fantastic shifter friendships, and great adventures await Sierra and her friends (buzzard shifter Ricardo, raccoon boy Alex, parakeet shifter Kiki, snowy owl girl Avery, and many more). Featuring guest appearances from beloved characters from Woodwalkers and Seawalkers. Uniquely exciting stories for all fans of fantasy adventures aged 10 and up. Unforgettably narrated by Timo Weisschnur. All Windwalkers volumes are available individually and can be read and listened to independently of the other books in the series.
