Bubbles and other laugh out loud novels...
On Allison's recommendations, I started reading the Bubbles' series by Sarah Strohmeyer. They're not quite as good as Evanovich's Stephanie Plum, but they're an easy and entertaining read. And, yes, at times, I even laugh out loud. I've read four of the five books so far and am going to pick up the fifth at the library in the next week.
Bubbles is a really ditzy blonde hairdresser who as part of her divorce settlement attended junior college (Two Guys) to be retrained for a new career. After failing tons of courses over 8 years, she finds that she's a natural for reporting. After all, what is a beauty parlor anyway but a den of gossip! She has a brilliant daughter who dyes her hair with koolaid and a hot boyfriend named Steve Stiletto. Strohmeyer admits to creating Bubbles at the kitchen table of Janet Evanovich. Definitely you can see Evanovich's fingers in this one.
The other two authors that I really enjoy reading that make me laugh out loud are Christopher Moore and Carl Hiasen. Holly introduced me to Christopher Moore with The Stupidest Angel and her Mom introduced me to Carl Hiasen. Both of them have characters that are out there to say the least. I think Moore is a bit more unhinged with his plots than Hiasen, but both of them write very entertaining and fun novels. These are all great summertime reads as they're light, hilarious and entertaining - just the way, summer should be!
