Aria is losing her mind to the anguish of her life past.
When Keir returns from death, she hopes it will save her, but his love is not enough.
Her emotions combine with her power, turning the essence of Love, Life, and Death into living creatures who wage war upon her. They want her power for their own, but Life and Death don't always play fair.
Keir and Jace struggle to help her, but when Bolt brings her into the undercaves of Jasta, it introduces entirely new elements into her life.
The question still remains, can the three men work together to save her or will they lose her for eternity?
