Argurma Monster by SJ Sanders

After one previous disastrous attempt to escape the dying planet, Dr. Beverly Ryder didn’t foresee much of a future beyond evading the amorous interest of Talech, her alien savior and the monster she’d help create in the laboratories deep within the bowels of the facility, and sitting on the long stretch of the island’s beach. She certainly didn’t anticipate another Argurma showing up on her island looking for Kaylar—the alien who had left her for dead. Zoreth was her ticket off Earth, an invitation she readily accepted even if it meant by stuck between two rival males at each other’s throats, but at least it was safe and promised the start of a new life she’d always wanted in space.

A new life that’s suddenly ripped out from beneath her when the ship, Garanga, goes down.

Forced to survive once more, Beverly has no recourse but to rely on the two males who want to claim her: Talech, the damaged and monstrous male she’d grown attached to, and Zoreth, a warrior secretly damaged from the death of his twin. And she’s going to need both of them because there are no pristine beaches. This time it’s an alien world filled with… zombies? Shit has definitely hit the fan and now survival means trying desperately not be eaten by a zombie and not to foolishly lose her heart to both Argurma males in the process.
