"Zeta Verity killed a man who deserved to live, and let a man live who deserved death. Now she has a limited amount of time to stop him and bring justice to Callisto.Born to excel but living in the shadow of her auspicious ancestors, Zeta is posted to the newly terraformed Callisto to work with specially bred horses. Killing a spy in possession of stolen data is just another day's work. She's not impressed by timid and scholarly Vladimir Bolokhovski, who arrives at the research base with a beautiful stallion he has genetically engineered. But when Zeta's superiors start disappearing and an arrest warrant is issued on her for spying, she discovers the man she killed is not what he appeared.Once Verity discovers they're all part of some twisted game, she needs the help of both Vladimir and the dead spy to find and stop the mastermind behind it all."

The greatest of the best, the least of the worst: both stand alone in a future divided. 4,000 years from the present day, the human race survives divided into a ruling genetic elite and a genetic underclass with neither the intelligence nor the will to revolt. Jed of the Shamrock is a 'star Archer', descendant of one of the highest Blood lineages in existence, and she carries with this a heavy responsibility and an adherence to a strict code of solitude and discipline. Gerald Wolff is a petty criminal and a halfBlood, a bastard resulting from the rape of a person of the lowest caste by a Blood aristocrat, shunned by both the low castes and those of the Blood. Thrown together by a hijack, Jed and Wolff must work together to keep their freedom when Jed's ship becomes the focus of sinister interests. Torn between the Code and her feelings for Wolff, Jed takes the Shamrock where she knows no man dares follow, where she must face her deepest fears and make a terrible choice.
