Beyond The Shadows by Jess Granger

Commander Yara has spent years living without the distraction of caring for anything - or anyone. It's a sacrifice she's willing to make. Yara has honed herself into the perfect heir to the Azralen throne, but a bloody coup could destory everything she's worked so hard for. She must return home quickly to prevent war, but the only ship available belongs to an Earthlen trader with no regard for authority - especially hers.

Cyn is a rebel, driven to protect those suffering at the hands of the Elite leaders of Azra. Using his alias to manipulate the lovely but icy commander onto his ship, he has to keep her from Azra long enough to ignite the revolution. But when he awakens a vibrant and feeling woman between that icy exterior, he gets more than he bargained for - love. Can Cyn find a way to convince Yara to join them, or will they get caught in a web of lies and deception that could tear them apart?
