After fourteen years being forced to serve the Order, Rían Fáidh is finally sent on his last mission before gaining his freedom, only to find a trap waiting for him. Unwilling to let one of their most talented mages go, the Order sends their personal assassin, the Mage Reaper, to dispose of Rían.

Meanwhile, Toua is a healer on the run from the cartel the Order sold him to in order to pay off his brother's debt. When he reunites with Rían again, pulled together by forces outside their control, they must learn to trust each other and the pack offering them sanctuary if they're going to survive.
