Rainbow Castle: The True Story of Sea Glass (Hardcover) (ISBN-13: 9798234083890)

After a tropical storm in Costa Rica, five-year-old Neomi and her beloved Grandma Sue head to the beach for their favorite hobby: searching for sea glass. But instead of the usual tiny treasures, they discover a mysterious heart-shaped piece of glass that begins to grow, pulling them into a shimmering glass globe and plunging them deep into the ocean depths.

Written by a real-life grandmother and granddaughter duo, Grandma Sue Johnson and Neomi Munoz Johnson, and accompanied by lovely artwork from Yadira Marin Mora, this enchanting tale celebrates the power of imagination, the bond of family, and the magic hidden in every treasure we find on the shore.
