Hi Dawn,
I also love the Janet Evanovich series, another very funny, very lighthearted series is by Marian Keyes, she is an Irish author, her books for the most part take place in either Dublin or London, they follow a family full of grown daughters. They are very VERY funny. Books are called: Watermelon, Sushi for Beginners, Angels, Last Chance Saloon, Rachel's Holiday and Lucy Sullivan is Getting Married. Another along the same lines is Making Minty Mallone by Isabelle Wolf, that is laugh out loud funny.
These books are lighthearted without actually being bodice rippers, I am from a family of female book snobs and we all LOVE these books!
Happy reading!
Jill
