What's The Moon Keeper About

Publisher Summary

Fall in love with this moving and magical picture book about a sweet, conscientious polar bear, the moon, and the special connection they share.

Illustrated with a classic feel and told with a refreshing voice, The Moon Keeper is a perfect bedtime story with gentle messages about friendship, impermanence, and nature that will appeal to fans of Kitten’s First Full Moon, Rabbit Moon, and Little Bear.

Emile, a very responsible polar bear, has a new job as moon keeper. He spends his evenings making sure the moon has everything it needs to shine its light over the night creatures.

Night after night he keeps watch over the moon—clearing away the clouds and telling the fruit bats to move along when they play too close.

Emile finds the moon nice to talk to in the stillness of the night. But what happens when the moon starts to change and slowly disappears? In a lovely and touching series of small investigations, consultations with neighbors, and a fair amount of worry, he learns that in life, things come and go—and it’s okay.

Zosienka’s debut as author-illustrator is the rare moon-themed picture book that shows the phases of the moon through brilliant childlike storytelling.

What Has Zosienka Said About The Moon Keeper

  • I was writing another story when the inspiration came for The Moon Keeper. I was wondering who might be reading that story and imagined my best friend’s baby girl picking up my book when she was old enough to read. And I wondered some more, what she would really like to read about? Her mother, my best friend, loves polar bears so I pictured him, a big white curious bear and saw him looking up into the night sky. My friend was also looking for a moon chart to hang in her daughter’s bedroom at the time and so emerged my second character; the full moon.

    Author's Note
  • I wanted to write a story that would reassure insecure children that they are not alone, especially at night. The moon is a presence everyone on earth can rely on . . . but even the moon disappears from time to time. So if the child can learn to trust that the moon will come back, they too can trust that they will be safe until their parents’ return.
