A murderer haunts the city, turning the unwary to stone. Between hunting this evil and corralling new arrivals, Flax struggles to guard both his life and his heart.

Quinn and Valerian have come through the trials of facing an undead lich queen and the perils of falling in love. Now they work to restore AURA to its previous strength and efficiency while navigating their new life with each other. Fortunately, they're not in this alone.

Kai Hiltas has taken over as the head of the research department at AURA and has become everyone's favourite workaholic, everyone except his lover Tenzin, who has had enough of his late nights and broken promises. As Kai tries to salvage his relationship, he finds a teacher for Quinn, who also happens to be one of Valerian's new officers, Flax Wolfheart, a sexy elf with trouble written all over him.

Flax has motives beyond simply teaching Quinn to control his magic. He's trying to recover from his own losses and failures, but he has a plan. The two newest elvish crossovers, Ash and Sage, are sizzling hot and might even like him. With them as backup as he tracks a deadly stone mage and figures out how to teach Quinn, Flax sees his chance to impress Val and snag a place by his captain's side. On the hunt for both danger and redemption, Flax's pursuit leads him ultimately down trails he never expected.
