I haven't read any medical/suspense books in ages. My treadmill is next to a bookcase and I just pulled this out and started reading. I've been reading a lot of non-fiction so this was a great distraction. And we know how much I like my medical lingo.
Gravity leads us into the world of NASA as we watch Emma Watson and her team preparing to be sent into space to stay for 4 months on the ISS (International Space Station). Watson is a physician who is in the middle of a ugly divorce from her husband, fellow physician Jack. We can still see the hearts around them when they talk though...angry hearts but hearts nonetheless.
Circumstances occur that cause Emma to be sent into space earlier, with another team. Once there, it's routing space station stuff, until experiments start going wrong. What happens next is an outbreak of "something" that is killing astronauts very quickly and very gruesomely. Everything is fast paced and we learn what this killer bug is at a breakneck speed.
Pretty exciting and fun book to read.
