This is a story about two cousins, one in America and one in Mexico, and how their daily lives are different yet similar. Charlie takes the subway to school; Carlitos rides his bike. Charlie plays in fallen leaves; Carlitos plays among the local cacti. The book covers the sights, sounds, smells and tastes of two very different childhoods while emphasizing how alike Charlie and Carlitos are at heart. Spanish words are scattered among the English text.
