A Dirty Business Mystery
I love these books.
There's something about the feisty heroine and cozy mystery style that just makes me want more.
And the antics of the New York crowd in this one are great!
Plus, the epilogue is a fabulous character by character update on what happens to them. I love that kind of thing, especially in a book like this where most of these characers probably won't show up again in subsequent books.
Personally, I would start at the beginning (Pushing Up Daisies), but really it's not necessary.
