My book group is reading Monkeewrench by PJ Tracy this month. The authors are a mother-daughter team and I find I can't tell there are two authors at all. It's the first book in a mystery/cop series, set in Minnesota. My husband and I both liked it. There are 4 books in the series now. I've read 1,2 and 4 - so far the first two were the best. I'll be getting the third one from the library this week.
If you like mystery and cop stories, and don't mind a few murder scenes, and you can get into the computer side of crime solving (since some of the characters are computer whizzes extraodinaire!) you might enjoy these books.
