Derelict

From the introduction:

A rogue black hole [Y0109+49155637] rushes toward “civilization.” In its gravity well, Y0109 carries the husks of ancient ships and forgotten technologies. A message in a bottle and rotten care-package from long-dead progenitors. Whenever Y0109 passes by an inhabited system, it collects more. Ships and corpses of careless treasure hunters, dead-space flora, unfathomable creatures that splice their eggs to battered steel hulls. During the long nights, the singularity molds, all creatures evolving to live off the black hole’s scant thermal radiation. Tread carefully, you, who approach Y0109. More powerful, more skilled salvagers have found their deaths and cold graves in eternally decaying orbits.
