Hard Hat Hank and the Sky-High Solution

Mighty Mighty Construction Site meets The Best Nest in this rollicking, rhyming celebration of teamwork, and the ways we can live in harmony with the natural world.

Hard Hat Hank and his hardworking crew are ready to build!

With blueprints in hand, Hank knows just what to do, but it isn’t long before the plans go awry. Fortunately, Hank has solutions for just about everything—until two birds decide to make their home on the construction site. There’s no nest in the plan! The birds need to go!

But after several humorous attempts to get the birds to leave, Hank realizes that it’s time for a new plan—one in which builders and birds can both enjoy their new home.

This book is part of the Disney Planet Possible Books program, aiming to inspire and empower young readers to take care of planet Earth through amazing stories that celebrate advocacy, conservation, and stewardship, kid-friendly environmental activities, and books manufactured with care in the United States.

“[The] book’s outcome serves as a cheerful reminder that even meticulous planners can benefit from flexibility and creativity—particularly when the result serves the needs of all parties involved.” –Publishers Weekly

“Construction fans and environmentalists alike will be hankering for Hank!” –Kirkus

Dream Submarine

Glide through the ocean with a young child in her cozy little submarine. See how marine animals brush their teeth, put on pajamas (by shifting colors to better blend in), and tuck themselves into sponge beds. Dive between towers of slumbering whales and see bioluminescent creatures paint galaxies in the abyss, then make a wish upon a sea star and let the Dream Submarine whisk you away. Author Charlotte Gunnufson gently guides readers to sleep as she introduces them to a host of mesmerizing sea creatures, while Cleonique Hilsaca’s colorful illustrations transform underwater environs into an imaginative dreamscape. Back matter features a map of the Dream Submarine’s journey, a deeper dive into the ocean’s zones and animals, and resources for further exploration.

Climb aboard the Dream Submarine and set your course for an eveningtide lullaby in this illustrated, illuminating journey of maritime enchantment.

Praise for Dream Submarine

“A delightful voyage well worth taking.” –Kirkus

“Sweet, beachy-hued digital renderings by Hilsaca suggest a striated watery environment, while Gunnufson’s maritime meanderings point the way toward pelagic dreams.” –Publishers Weekly
