Eleanor and her sisters Abigail and Meredith live in the central kingdom of Yeria, a walled-off civilization surrounded by dense forests. Abigail is one of the Weavlings, a group of people who have the ability to weave the threads of the universe, and manipulate different Elements. When Abigail falls ill to the sickness that plagues many Weavlings, Eleanor will do anything to save her, including traveling beyond the walls, where she finds out that the ancestry of the royal family of Yeria is not all it appears to be.

When Hell declares war on Heaven yet again, fallen double agent Jael finds herself caught between sides. As she plays one leader against another, she begins to discover that not everything about this war is what it seems - and the more she learns, the more danger she finds herself in, and the harder it is for her to pull herself away.
