The Last Human

But most days, she doesn't feel like the most terrifying creature in the galaxy. No, most days, she's got other things on her mind. Like hiding her identity among the hundreds of alien species roaming the corridors of Watertower Station. Or making sure her adoptive mother doesn't casually eviscerate one of their neighbors. Again.
And most days, she can almost accept that she'll never know the truth about why humanity was deemed too dangerous to exist, or whether she really is - impossibly - the lone survivors of a species destroyed a millennium ago. That is, until an encounter with a bounty hunter leaves her life and her perspective shattered.
Thrown into the universe at the helm of a stolen ship, Sarya begins to uncover an impossible truth. Humanity's death and her own existence might simply be two moves in a demented cosmic game, one that might offer the thing she wants most in the universe - a second chance for herself, and one for humanity.
