Janet Evanovich's Stephanie Plum series is one of my favorite pick-me-ups. I am linking to the latest, Twisted Twenty-Six, in this review but I've only read to book fifteen, plus four "between the numbers" books.
Let me tell you about Stephanie. She's of Italian and Hungarian heritage, in her late 20s or early 30s (it's never clear), is smart but kooky, loves cake, and works as a bounty hunter in Trenton, New Jersey. Her cousin Vinnie offers her work at his bail bonds office after she is let go from her executive position in lingerie sales. She's divorced after a short-lived wreck of a marriage and in love with two men: Joe Mirelli, a childhood friend and police detective, and Carlos "Ranger" Manoso, a mysterious Special Forces guy. She lives in a retirement complex with her hamster, Rex, and has Sunday dinner with her mother, father, and Grandma Mazur who is quite the pip. They eat an amazing array of lasagnas and roast meats and Stephanie supplements these meals with many visits to Tastykakes, Dunkin Donuts, Cluck-in-a-Bucket and various local delicatessens. There's a lot of driving around in a 53' Buick called "Big Blue" trying to capture "skips" and many local funerals that must be attended by Grandma Mazur. The last two books I read included a pet monkey named Carl who plays Nintendo. I think that gives you the overall vibe.
Many of the Stephanie Plum books are part of the Lucky Day collection in OverDrive, which means you can "skip the line." Lucky Day titles are immediately available on a first-come first-served basis and are offered in both eBook and audio formats. If you've lost track of Stephanie over the years, this gives you the chance to get reacquainted. If she's new to you, you are in for a real treat.
