From publisher blurb: The bridge was silent except for the whirr of the ship's air filters. Nima, the sensor operator, looked up from her screen. “No signs of intelligent life, no com traffic, no artificial light,” she said quietly. “Atmo?” captain Nastasia asked, loud enough for everyone on the bridge to hear. “Dense, probably corrosive...” Nima was cut off when a shadow fell over the bridge. The sun was eclipsed by an enormous entity speeding silently towards the ship. Collision alarms shrieked on the bridge. The crew of the Akhander watched the gigantic wreck descending towards them, a dark body of unrelenting force crowned in starlight.
