The Nameless Cryst (2011)

Set in 7028 in the galaxy called the New Expanse, space smuggler Kyne Dibasi must pay off his two-year debt to the Hashin smuggling cartel by tracking down a woman named Cuaras and returning her and her "stolen" cargo to Bahir Hashin. However, Dibasi learns along the way that Cuaras is more than she seems, and her precious cargo is in fact the stone that wiped out nearly all life on Earth 4000 years ago. And when renegade scientist Dr. Rogaud Loore comes into the picture, the two must reluctantly join forces in order to keep the stone from falling into the hands of their old nemesis.
