Stella, Star of the Sea — Marie-Louise Gay

Stella and her little brother are spending the day at the beach. Stella has been to the seashore before and knows all its secrets, but Sam still has a lot of questions. Does a moonsnail come from the moon? What can you buy with a sand dollar? Stella has answers for them all. The only thing she's not sure about is whether Sam will ever come into the water. Through exquisite watercolors, this book brings to life a perfect summer day and the sweet and funny relationship between an older sister and her baby brother.
