In the world of Ithlin darkness resides. Sickness and the monsters they create run rampant. There are but few groups who stand up for a bright future. The Paladins of Cainen and the Birds of Plague. Whereas the Cainen soldiers focus on protecting the peace between territories the Birds focus on healing the sick and hunting the monsters.
Being a high school senior is challenging enough, but combine that with the fact that you and your friends have the power to transform into birds, and are training to take over the guardianship of the Sensa stones, ancient powerful relics that grant the holder magical powers, and you get the Avian Apprentices. Join teens Maggie, Sara, Charlie, Clarisse, and Derrick as they navigate their new confusing responsibilities and find out that their already strange lives are about to get a whole lot harder.
