Juana MÉndez and Diane Conrad are going to save each other's lives. Not with super heroics, but with a friendship that gets them through everything. And those girls are always up to something—eating goat burritos on July 4th, sneaking up on a garage roof to watch a couple kiss and wonder about romance, and surviving the meanest kid in school. Then another summer arrives, and ends in heartbreak and hope for the best amigas.
