Award-winning science fiction author Mary Robinette Kowal consulted with a NASA astronaut to craft her first picture book story, accurately describing how living on the moon differs from life on Earth. Beautifully illustrated by Diana Mayo, Molly on the Moon is the tale of two siblings adjusting to their new home.

When Molly and her family move to the moon, they can only pack the essentials—just one toy each for Molly and her baby brother, Luke.

Luckily, Molly has a big imagination. A packing crate becomes a fort, a tarp becomes a witch’s cape, and some cans become a tea set. Baby Luke, on the other hand . . . has blocks.

Molly doesn’t want to share. At first. But then she realizes that when you’re on the moon—or anywhere else—a big imagination and being with someone you love can be infinitely better than all the toys in the universe.

Inspiring and imaginative, Molly on the Moon also includes fascinating facts about the moon’s environment, revealing how the differences in gravity, temperature, and time would affect our lives.
