Hiding Space — Linda Andrews

Commander Brongill of Da'Hap heads the expedition to Earth in hopes of finding the survivors of an ancient crash and the key to Terrill's survival. But Brongill knows first-hand how his race treats its saviors and decides to spare the human hybrids a torturous death by making certain they never reach Terrill. His mind is firmly set on revenge until he meets her…

Alderina Wedgen wants nothing more than to raise her three children in peace. What she gets is kidnapped by aliens, seduced by a secretive commander and nearly blown-up. Facing a common enemy, she has no choice but to form an alliance with a man who once considered killing her--a man who is relentless in pursuing what he wants.

But while the universe is vast, Ally and Brongill soon find that there is no hiding space and to survive the trip they'll have to risk more than their hearts and lives.
