The Salbine Sisters - Sarah Ettritch

She gave up everything to become a Salbine Sister, member of a religious order of powerful female mages. But when Maddy nearly dies while trying to draw forth elemental fire, she learns that Salbine has withdrawn from her the gifts every sister works to master. Feeling trapped in an order to which she no longer has any right to belong and believing herself unworthy of the love of Lillian, one of the most powerful mages in the sisterhood, Maddy begs the abbess to let her travel to another monastery to research her condition.

On her journey, Maddy's faith in both herself and Salbine are tested to their limits. When she attempts to draw fire and fails horribly, frightened townsfolk throw Maddy into prison. Fearing that the abbess will never learn her fate and rescue her, Maddy resigns herself to a short and brutal life.

The only bright spot in Maddy's existence is Emmey, the pickpocket with whom she shares a cell. Through her and the steadfast love of Lillian, Maddy learns that Salbine's purpose is not always the same for everyone, and that love and compassion are more valuable than magic.
