With her life hanging by a thread, Kaja had little time to consider Eithne's offer of aid. Now, free of her affliction, she bears the consequences of that decision. Stuck among her former enemies, caught navigating the nuances of lies and politics, she's presented with little choice but to accept the out offered by Cathal, leader of the Scáthanna. But Cathal and his team have troubles of their own as an invisible enemy haunts their steps. If Kaja helps them, she'll be targeted as well, and when dealing with a faceless enemy, the only way to survive is by carefully choosing allies and tempering trust. Failure could cost their lives.
