Edge of a Shadow, Part Two (en Inglés) - J.E. McDonald

Nothing is as it seems.

Ander and Sashen may have escaped imprisonment at FBI headquarters, but they've landed in a whole different mess. Crossing to Fey, Ander doesn't know how he'll get home, and these enemies turned lovers have discovered elusive creatures have been pulling the strings, ones who manipulate time and memory.

They can't fight what they can't remember.

With Ander's teammates still lost, and Sashen's sister trapped in Wickwood, danger lurks in every shadow. Complications deepen for the pair when they arrive in Ashentreach. Who is friend and who is foe is cast into doubt when unknown entities can influence the past and forge new futures. And the queen's next orders are fraught with danger: align with giants to dominate the demons, for the Cassad Forest still burns and the walls between realms continue to crumble.

Making a deal with the devil might be the only way their worlds survive.
