Surin Lost Alien by T.J. Quinn

From all appearances, the dragon who fill the skies, burning cities, and rounding up innocent humans, are the reason Earth fell. The dragons and their slyth overlords are despised among those who survived the invasion.
Surin was ordered to torture and kill Eloise. Her fate is sealed…
Until Surin discovers she is his fated mate. While Surin is overcome with guilt for torturing Eloise, he’s determined to save her at any cost.
To heal her, Surin uses his blood in a claiming ritual. . . an act that ties them together permanently. Though Surin longs to make Eloise his in every sense of the word, he doesn’t think he has the right.
He’s the one who nearly killed her. Once she heals, he’ll leave her. All is going as planned until Eloise’s memory returns and she recognizes Surin as the alien who tried to kill her.
Before Eloise can escape, Surin kisses her, stirring feelings she didn’t know existed.
These former enemies learn they must work together to survive. Friendship soon turns to passion and love, but Eloise doesn’t know the full scope of Surin’s crimes or what the asseptians have planned for him.

Will Eloise risk her heart to save Surin? Or will he sacrifice his life to save her?
