Lady Gwendolyn lo Havil is an Ava Spring, born to heal others and lead the Season Avatars of her generation. Season Avatars with divine magic must work in groups of four to save the country of Challen from Chaos Season, times when all of the seasons appear at once. When the current Ava Spring dies in a riding accident, Gwen must find the other three Season Avatars she will link with. But two of them are missing, and with Gwen's own magic crippled by a cursed pottery shard, she will have to use all of her skills to find the Avatars scattered across the country of Challen. During her journey, she meets a stranger who claims to know the shard's origin. Is he truly an ally of the Season Avatars, or is he trying to stop them from uniting?
