Love in a Nutshell by Janet Evanovich and Dorien Kelly
Kate has been having a rough time of it.  She is recently divorced, lost custody of her beloved poodle, and is living in her family’s wreck of a summer home (the Nutshell) which she is determined to restore and make into a bed and breakfast.  Biggest problem is she’s broke, some idiot owns the mortgage on her house, and she just got fired for serving skunky beer to a customer.  So she marches right down to the brewery that made the skunky beer and demands a job.  She gets it, and more.  If she finds out who has been sabotaging the brewery she’ll get a $20,000 bonus.  And she gets to work closely with her gorgeous boss, Matt, so how could anything possibly go wrong?
In typical Evanovich fashion things go astoundingly wrong, but this is a standalone mystery/romance so you do get a wrapped up story unlike the whole Joe/Ranger thing that’s been going on in her popular numbers series.  If you like quirky humor, cutesy romance and a surprisingly good mystery you may want to visit the shores of Lake Michigan in Love in a Nutshell.
If you’re a fan of the Stephanie Plum books on audio you’ll really enjoy this since the same reader, Lorelei King, reads both.  However, be warned, you’ll be confusing Kate Appleton with Stephanie Plum (she really likes fruit doesn’t she?) in your mind.
