Starchaser by Tonya R. Moore

Starchaser Laila sets out across the galaxies in search of the ultimate trump card to help her to wrest control of the leviathan ship, Hegira from those who would seek to steal her ancient birthright. Laila’s pride and passion wars with love, fear and her inferiority complex caused by her luminous and beautiful rival Sumida.

Starchaser Sumida is accompanied by the mercenary, Bex Atria and a psychotic alien named Klang. Her survival will depend on three things: dumb luck, Bex’s talent for weaseling out of a sticky situation and Klang’s penchant for secretly murdering anything that threatens the well-being of his beloved Bex.
