Saved By The Cyborg by Alyse Anders

With the enemy closing in, a cyborg must do everything he can to save his mate.
Eagan has a brilliant tactical mind and was instrumental in the cyborg’s defeat over the Sholle, but in the years since the war, he’s been on his own. With the arrival of a Sholle scout ship, he’s pulled back to active duty and changed with not only saving the lives of the Grus but also a ship full of human women. When he meets his mate, Beth, Eagan’s world is turned on his head. Now, he must not only find a way to defeat the Sholle but save Beth from the Grus who want to keep them apart.
