Siphany and the Whale - Susan Jane Bigelow

You blow up one crappy little space drone, and everything goes to hell.

Siphany was just trying to be nice when she returned the drone she'd sort-of-accidentally blasted a hole in. But when its owner tries to kidnap the reclusive space mapper and steal her beloved ship, Siphany teams up with pint-sized robotic psychopath, Lurbira Call, to make a daring escape.

Soon Siphany and Lurbira, along with unwanted passengers Isan, the undead teenage cyborg; Siphany's enigmatic former lover and Sovene spymaster, Qas; and moody, electrically beautiful fighter pilot, Pati, are all caught up in a deadly game of spies, starships, and interstellar war. When everything comes to a head, Siphany and Lurbira must find a way to face their tumultuous pasts in order to really, truly find freedom at last.
