City of Ruins: A Diving Novel

Years after stumbling across her first Dignity Vessel, Boss now leads a team of people searching for "loose" stealth technology. She takes a team to Vaycehn to investigate a phenomenon called death holes, thinking they might lead her to stealth tech.
Captain Jonathon "Coop" Cooper and the crew of the Ivoire finally find a way out of foldspace despite their damaged anacapa drive. But he soon realizes the ship's return to normal space is anything but normal.
Coop and Boss hold the answer to questions both seek. But what they discover will change everything.

"City of Ruins has two great strengths going for it. One is the characters. Rusch does a marvelous job of bringing even minor characters to life.... The other appeal is the constant tension....Each scene is a taut wire, ready to snap."
