Waiting is hard. In a gentle multigenerational story that blurs the boundaries of real and imagined, Noah waits on shore while Nana fixes their sailboat. The boat will take them out to sea where the seals live, and Noah can hardly contain himself. In the meantime, he sculpts his own seal out of sand. Noah collects shells for the seal's speckled back, spiky dune grass for whiskers, two shiny pebbles for eyes, and a smiling line of seaweed for a mouth. He lies beside his new friend to watch the rolling sea until a storm blows in and Noah must take cover. Later, he wonders: did his seal swim away? Readers will delight in pondering the mystery too in this sun-splashed book for young adventurers--an essential summer-vacation read.
