Rusch is using the Diving novellas from Asimov's to make books. This is the first one out so far.
The wreck isn't in water, it's in space, and diving is much more dangerous than it is on Earth. Boss runs into a Dignity Vessel that has stealth tech, she brings divers back, and loses two of them to the tech. Her time period has lost a lot of Earth technology so while they have some small stealth, they don't have anything like this. Later, she remembers that the Room of Lost Souls, where she was left when she was young (and her mother died), must have also been stealth tech from Earth. She took divers there and one of them died. It turns out that only some people -- the empire has found 13 of them -- have a genetic marker that lets them be in the stealth field without dying. She and her father both have the marker, but he's on the side of the empire. She wants to get rid of all the stealth tech.
I not only really like this, I'm two nights into the next book: City of Ruins. You should really try these.
Kris has a lot of other great books, too, in many other genres, have a look.
