Query: I loved this book! It was so much FUN!

Janet Evanovich is a wonderfully funny writer! Stephanie is such a character and after meeting her grandmother we know where she gets it from. I can't wait for more from this author. I hate to finish one of her books because it's so long until the next one is out. A great relaxing, humorous way to spend a vacation day!
