It?s nighttime in the sky above, and Mother Moon calls her son to bed. But he?s down below, floating on the sea in a makeshift boat and playing with his web-footed friends. How will Mother Moon find her child and bring him safely home? In this beloved bedtime tale, reprinted in board book format, Barbara Helen Berger reminds us that a mother?s love knows no limits...with the help of a lot of otters.
