While You Sleep cover

By Jennifer Maruno & Miki Sato

While You Sleep

Breathtaking collage art and exquisite rhyming couplets showcase fantastical dreams as the natural world is prepared for a new day in this gentle bedtime book.

As the day ends and a little girl is put to sleep by her mother, night-helper bunnies work their magic to tidy and polish the world. These helpers paint flowers, dust butterflies, and charge rainbows to make the world a beautiful place to wake up to.

Miki Sato’s collage art, which combines paper, textiles, and embroidery silk, creates a three-dimensional dream world that is rich in detail and texture. Jennifer Maruno uses soothing rhyming couplets that celebrate the beauty of nature, creating a uniquely magical world.

It’s dreamlike and silly and ultimately very comforting.”—School Library Journal, Fuse 8
