I've been finding so many excellent nonfiction titles that I'm having to give myself a little speech about glutton and book lust!
Here are some that I've written down lately:
The Girl from Foreign - recommended by Lotus
Galileo's Daughter & Death by Black Hole - on Stefanie's list
Faust in Copenhagen & The Ancient Tea Horse Road & Fatal Passage- Melanie's blog
The Last Stand of Fox Company - over at Colleen's
There is also a long list of fiction. My reach so far "exceeds my grasp"!
