The third book in the slow-burning Norse-inspired time-bending romantasy, complete with dragons.

The people of Unison were betrayed long ago, but who was the shadow-woman instrumental in bringing about the harsh terms of the Agreement?

Unintentionally breaking those terms, Emma is thrust into her past and forced to relive all the heartbreaks of her rotations on Unison, while the Librarian falls into a trancelike state, unable to communicate.

Erann and Sereh must use the clues left by the Librarian to help the pair. But when the answer involves the bitterly hated Rankil, Sereh determines she's the only one who can approach him, risking herself, for the good of her friends.

Can Sereh help Emma return to them, or will Rankil prevent her from doing so? And if Emma is lost forever, who will aid them in their attempts to reclaim all that's been stolen? Will Unison be betrayed again?
