She's determined to stay alive for her family, keeping hope in her heart for her hero, but when devastation strikes, her sanity takes a hit. Quin Quin Kavanagh lives for Layla. Now that she's gone, he's suffering a slow death. There is no limit to what he'd do to get her back, but the clock is ticking, and every direction he turns leads to a dead end.
With lives on the line and hope slipping away, Quin puts his faith in two unlikely allies. But even if he gets Layla back, she won't be the angel he remembers. The Enemy With Layla in captivity and their adversaries outnumbered, the Dark Guild holds the power, and they plan to use it to unleash hell on earth.
