We listened to the audio of "Winter Study" and found it quite good. Will have to get another Nevada Barr for when we travel.
If one likes archeaology, Egyptology, the late 1800's, you might enjoy Elizabeth Peters titles about Emily Peabody and her husband, Radcliffe Elliott. In the first book, the couple aren't married yet but, of course, that's where it ends. Here's the comment from our library on the first in this 18 book series, entitled "Crocodile on the Sandbank":
"Amelia Peabody, that indomitable product of the Victorian age, embarks on her first Egyptian adventure armed with unshakable self-confidence, a journal to record her thoughts, and, of course, a sturdy umbrella. On her way, Amelia rescues a young woman and helps her elude her rascally lover."
I find myself having a good time reading these books. Peters also writes under the name, Barbara Michaels. I want to see what she includes under another name.
