I have 2 authors I love (besides Evonovich)
Diane Mott Davidson - has a catering business. Includes recipes -- example title: Sticks & Scones, Fatally Flakey
Joanne Fluke -- has a bakery. Includes recipes (YUMMY ones) -- example title: Carrot Cake Murder, Candy Cane Murder (has the BEST recipe for cookies in this one).
They're both murder mystery writers, easy reading, and the murders almost take 2nd place with the businesses. I recommend looking at their websites and starting with the first book.
ENJOY!
