The Sisterhood Of The Traveling Pants by Ann Brashares
The book follows four best friends—Lena, Tibby, Bridget, and Carmen—who discover a pair of jeans that miraculously fits each of them despite their different body types. Dubbed the Traveling Pants, the jeans become a symbol of their friendship and a way to stay connected as they spend their first summer apart. As the pants circulate among the girls, they experience a series of personal growth and life-changing experiences, from first loves to family conflicts. The story is a heartwarming exploration of the bonds of friendship, the pains of growing up, and the belief that a bit of magic can appear in the most unexpected places.
