He heals others while she saves lives in the shadows. But when danger strikes, they'll have to save each other.

Niri Healer Nirrn lives by logic, order, and the healer's oath. But everything unravels the moment he stumbles upon Islae?an underground human medic risking her life to treat the forgotten and discarded. She's reckless. Stubborn. And maddeningly brilliant as well as beautiful.

When her illegal clinic is destroyed, Nirrn does the unthinkable: he brings her into his world. Now they're on the run, hunted by a corrupt system that sees their bond as a threat.

Their alliance was supposed to be temporary. A way to survive. But as danger closes in and desire builds, Nirrn realizes Islae isn't just another patient to protect...

She's his mate.

And he'll tear down the galaxy before letting her go.
