Agnes and the Hitman / Jennifer Crusie and Bob Mayer 368 p.

I owe the recommendation for this highly entertaining tale to Cindy. Agnes, in addition to working frantically to get a new cookbook launched, has problems with the business of life in general. She's engaged to a loser, someone is trying to kill her dog, a handsome and highly skilled hitman shows up in her kitchen without warning, and she has a week to plan a flamingo-themed wedding for some old Mafioso friends. The outlandish events are anchored by realistic (and funny) dialogue and believable emotional responses.
