Princess Ella and Princess Joey of Bubbleville are playing together in a beautiful flower patch when raindrops begin to fall. As the shower sparkles around them, Princess Ella tells her little sister about a magical place called the Rainbow Slide, which appears where sunshine, rain, magic and lots of love all meet. Eager to find it, the princesses call for King Daddy, and their ordinary afternoon blossoms into an extraordinary family adventure. Joined by Duckle, Ella's bubbly little duck, and Freddie, their lovable dog, they travel by royal car, airplane, submarine, camel, and canoe, following the rainbow across forests, oceans, deserts, rivers, and towering cliffs. Along the way, they encounter surprising sights, silly moments, and plenty of reasons to laugh. But nothing can prepare them for what waits at the end of their journey: an enormous rainbow slide soaring through the clouds, with a magical ice cream celebration below. Filled with warmth, wonder, humor, and richly imagined illustrations, The Rainbow Slide is a story about sisters, family, courage, and the joy of believing that something wonderful may be waiting just beyond the next bend. A playful bedtime adventure for children and families who know that the best journeys are the ones shared with the people, and pets, they love most.
