Enslaved — Kate Hill

To end the war between their kingdoms, Darkrock and Strongsea are ordered to marry and select a female mate to be shared between them. Bitter enemies, the men rebel against the notion of being bound for life, but despite their opposing personalities, they can't control their passion for each other.

When Radiance, a merchant from Earth, crashes on the planet Shandra, she is taken into slavery and bought as a gift for Darkrock and Strongsea. Both desire the exotic human slave, but Strongsea's compassionate nature drives him to protect her against Darkrock's lust.

Soon Radiance and Strongsea realize there's more to Darkrock than his harsh veneer, but only together can they draw out his inner man.
