Sisterhood of the Traveling Pants by Ann Brashares

I was reluctant to read this, thinking it would be "fluff", but I LOVED it! I thought it was well written, the characters felt realistic and the issues as well. I have only read two so far, but I will throw in the caution that some of the issues in the last book look to be a little more realistic (pregnancy scare, more serious involvement with boys). In the first two, adult issues were hinted at more than explained. I liked that the characters were flawed and I loved the quotes that started each chapter.
