From the creator of Not Quite Narwhal comes a story about a young girl determined to impress her older sister by building elaborate sandcastles, even if that means standing up to the ocean and its smash-happy waves! Jules is going to build the biggest, the fanciest, and the most excellent sandcastle. Her sister will be so impressed. But the ocean has other plans. Jules keeps building bigger, fancier, and more excellent castles, and waves keep smashing them. And when the ocean takes her bucket, that is the final straw. Jules is going to take a stand! From beloved storyteller Jessie Sima comes the tongue-in-cheek story of the sand, the sea, and sisterhood—told with her signature warmth, timeless humor, and delightfully playful illustrations.
