Seven-year-old Alicia and her parents are enjoying the annual festival celebrating Mexico's independence. There are mariachis strolling across the festival grounds, folkloric dancers twirling in their colorful costumes and brightly colored booths lining the plaza. But the hot day has made Alicia thirsty. Her mother suggests aguas frescas and points to a booth lined with jars of brightly colored fruit juice: there's watermelon, strawberry, mango and even papaya. The watermelon juice is so delicious that Alicia drinks it all. "Mami, this tastes better than that red soda I drink after soccer practice. Can we make some of these at home?" Soon, Alicia is perfecting her own recipe and sharing it with her teammates after soccer practices and games. In this bilingual picture book for children ages 5-8, a young girl discovers a treat from her mother's Mexican-American childhood and becomes her friends' favorite player with her healthy, frothy fruit drinks.
