Autumn escapes from Eclipse’s custody with a mysterious ally, causing the unstable mercenaries to lose their minds. Years pass, and Autumn races from city to city searching for a safe haven from her hunters. Just when she finds peace, her sanctuary is shattered as Andrew Sheppard attempts to “save” her from a mugging. Andrew is lethally wounded, and Autumn alters his genetics in order to save his life. With a weakened Autumn and an inexperienced Andrew, will the two be able to fend off the soldiers that are tracking them down? As the unaligned combatants Hephaestus and Tai appear on the battlefield, who is an ally and who is a foe? Surrounded by enemies, Andrew and Autumn must learn to trust one another or perish at the hands of the relentless mercenaries.
