The Ancestors' magic is not what it seems . . .

Ryn and Zo saved the Library from immediate destruction, only to put off the inevitable. It's just a matter of time until Zmej comes back to finish the job. Meanwhile, Zo tries to hide the loss of his Healing Magic, while Ryn fights for her rights as an Ordinary. To make things worse, the Ancestor elite are busy evicting them from the Library and their homes.

When Ryn finally discovers a clue to her adoptive father's location, it's a race to get to him before Zmej does. Her father has vital information about magic, the Ancestors, how the Library works, and what Ryn truly is. But between the race to save the Library and searching for a cure for Zo, she might just discover more than she ever thought was possible about her biological mother and father, magic, and the fate of the Heart Tree.
