Evelyn -- the product of a once-great power's condemned scientific endeavors -- is always on the run, staying just one step ahead of Sequel Corp, an ancient mega-entity whose survival depends on her capture. Always slipping between worlds, adapting and surviving among unsuspecting humans. Her latest refuge, the ocean planet Huyto, offers temporary sanctuary until a single slip craft brings her hunters perilously close once again. Desperate for escape, Evelyn makes an impossible offer to Gabriel, a gun for hire, and his crew. But as they narrowly evade a planetary catastrophe and jump into deep space, Evelyn's secrets begin to unravel, hinting at powers beyond comprehension. Gabriel's crew is torn between profit and suspicion, caught in a whirlwind of cosmic stakes, deadly relics, and the mysterious figures who wield them. As Sequel Corp tightens the net and other interested parties begin to take notice, they find themselves becoming fugitives and marked targets. Stumbling from one planet to the next, leaving a trail of destruction in their wake, Gabriel and his crew's desperate journey is anything but smooth and as they attempt to outrun their problems, they risk colliding with forces that hold the very fabric of the universe together. Whether they will find refuge among the stars -- or unleash powers beyond their control -- only time will tell.
