Stella and her little brother are spending the day at the sea. Stella has been to the sea before and knows all its secrets, but Sam has many questions. "Where do starfish come from? Does a catfish purr? Does a sea horse gallop?" Stella has an answer for them all. The only thing she isn't sure of is whether Sam will ever come into the water. Evocative watercolors bring a diaphanous day at the beach alive in this perfect summer story. Gently humorous, the book also captures the relationship between an older sister and her baby brother -- a responsibility that can be both lots of fun and very trying.
