Banic - Alien Berserkers of Izaea, #1

She's a doc on a mission. He's a beast with a heart of gold. Dr. Beth Godwin arrives on Parac'Norr with one goal in mind: curing the Blood Rage mutation that plagues the alien warriors. But she didn't expect Banic, the most feared feral on the planet, or her reaction to him. A caged monster, she knows she should stay away from him. But instead of a beast, she finds a man with soul-deep scars who trusts no one.
But when the secrets in his DNA unravel and threaten to change everything, she must make a choice. Because loving Banic means risking everything. including her heart. He was a monster, until an angel taught him how to love. Banic has forgotten anything other than pain and rage. Ruined by Blood Rage, he knows he's not worthy to kiss the ground the beautiful human doctor walks on. She holds his lige in her delicate hands and he knows when she's done studying him, he's taking a one-way trip out into the brutal desert.
Even though his life is already forfeit, he can't help wanting her. needing her. He craves her like a drowning man craves water and he can't stay away. When an ancient enemy returns and takes her, he must confront the demon under his skin. One things for sure, he'll tear apart the galaxy to save her. Even if he has to damn himself in the process.
