Gravity is mildly retro, having been written in the 1990s and features several space shuttles, but it’s one of the most fast-paced books I’ve ever read. It’s as much a medical thriller as a science fiction adventure.

Estranged from her husband, a brilliant research physician achieves her dream of running experiments on the International Space Station, but one of the experiments turns wildly lethal. Rescue missions run into their own troubles.

I don’t want to give any more away.

Recommendation: Read it! I’m looking forward to reading more of Tess Gerritsen’s books.
