Can you identify the author/title of a big sprawling sci-fi thriller in which an American astronaut recovers a small alien object in Earth’s orbit? The object turns out to be an interstellar probe, one of many. Another character, a man from China or Hong Kong, is salvaging more of these probes from undersea. There’s also a woman who was terribly injured but patched together with advanced technology. A conspiratorial group is hunting down people who are in possession of the probes. The story takes place in the near future, when sea levels are higher.
I think the novel was published in the 2010s. I do recall that the author is a scientist (I don’t think it’s David Brin.)
