Ever since contact was first made between humans and the alien idomeni, tensions between the two races have been frequent and bloody. As the first genetically altered human-idomeni hybrid, former Captain Jani Kilian serves as a lightning rod for the anger, outrage, and hatreds of both sides. And now the ex-soldier finds herself in the unwanted role of diplomat—serving the interests of her hybrid enclave, Thalassa, the only place in the universe that welcomes renegade humans, hybrids, and aliens alike.
But the all-powerful Commonwealth intends to bring Thalassa to its knees, and the time for diplomacy is at an end. With death surrounding her, Jani Kilian must return to where her nightmare began and once again take on her most powerful persona: warrior. For as the game approaches its inevitable conclusion, she knows only two options remain: victory . . . or extermination.
You need to be patient with a series where the author hints rather than explains and doesn't feel a need to tie up every loose end or give the complete backstory. If you have that patience then this is a wonderful series with a compelling main character and gripping storyline. One other note, the focus here is on the characters and culture with the science part of the sci-fi quite secondary.
