Finished: Oxygen, by Carol Cassella. Recommended.
Started: Bury Your Dead, by Louise Penny. I'm having a terrible time -- I want to read this book as fast as I can because I can't wait to find out how it all turns out, but I want to read it as slowly as I can so I can savor every word. Read her books in order (the first one is Still Life) so you can get to know the characters gradually, as you would in real life.
