Books like Sisterhood of the Traveling Pants / Second Summer of the Sisterhood / Girls in Pants

These books were great and I am waiting for the fourth book to come out...(as well as the second movie). Just an all around great story about four girls who share a lifelong friendship and many adventures together. The action never stops..lol It kind of reminds me of the kind of things that Judy Blume might write about.It was a nice change of pace in my classics collection (young adult series). Sure it has its real life lessons about growing up and dealing with change but it was just a plain wholesome "good read" at its finest. You didn't put these books down with a heavy heart, just a big smile...wondering what will happen next summer in "THE PANTS". It kind of reminded me of Joyelle, Alana Jen and Ginny if you just changed the names of the girls in the story a bit:)....What to read next....hummmmm. I will have to consult my list. This is a hard act to follow. You can bet that any book that I am reading will be put down when book 4 comes out!!!!!!!
