Star bringer / Tracey Wolff and Nina Croft.

"The sun is dying...and it's happening way too damn fast. With the clock ticking, the Nine Planets' only hope of survival rests on a fancy space station and the alien artefact it's carrying. Which is why it really sucks when some jackass doesn't want the universe saved and blows that station up--while you're still on it. So if your only choices are flaming death or stealing a flying hunk of space junk--you pick that busted-ass spaceship. Even if it leaves seven strangers with deadly secrets trapped together: a princess, a prisoner, a con artist, a warrior, a priestess, a mercenary, and an asshole in charge of us all. Now every faction in the galaxy is hunting this ship--from the Sisterhood to the Corporation, and the rebellion's joining in on the fun, too. We just need to stop drinking, fighting, and screwing long enough to evade them all and save the freaking universe...somehow. Because apparently the only thing standing between a dying sun and ultimate salvation is seven unlikely misfits...ahem, heroes"--
