Qeya (Heaven's Edge #1‪)‬

Qeya has spent her life aboard a ship adrift on heaven's edge. Being Royal means more than being groomed to rule her home planet. Though young, she can wield a scythe blade and suck the life out of her enemy, literally. That her whole life has been planned out for her, including whom she will marry, has never bothered her...until her ship is attacked.

Forced to lead before she is ready, Qeya must find a way to put aside ancient prejudices so they can all survive. Old enemies must form new alliances if they are to last the night. For no one knows the secrets of the new world and only a few can survive the living nightmares at heavens edge.
