The Unicorn Rider — Nick Marsden

Upon his return to Terah, Gaelan True-Blood's first act as Protector is to use his new-found power to destroy the immortal Lord and Lady of Terah.

Horrified by what Gaelan has done, Ariel Boreen and her unicorn companion Michael wonder what has driven her childhood friend to attempt to resurrect an ancient evil. Barely escaping with their lives, Ariel and Michael embark on a quest to fight against the monster Gaelan has become.

Again, the Never-Born appears to guide their fight. But Ariel has doubts about the mysterious being. Is he trying to save Terah, or hasten its destruction?
