Bobbie Faye's Very (very, very, very) Bad Day by Toni McGee Causey.
Having a crummy day? This book is for you. Has a little bit of everything--humor, mystery, romance. It came out in 2007 (I'm a little behind in my reading), and I couldn't be happier that there are now other Bobbi Faye books out there. Must. Find. Them. Too fun for words.
