In the first novel of the series, the reader is introduced to four high school students: Lena Kaligaris, Tibby Rollins, Bridget Vreeland, and Carmen Lowell. They have been best friends since birth (their mothers attended prenatal exercise classes together). The summer before their junior year of high school, Carmen finds a pair of old jeans that mysteriously fits each girl perfectly, despite their different sizes. This leads them to believe that the pants are magical. They share the "traveling pants" among themselves over the summer while they are separated.
