Jack loves everything about his adventures with Grandma Goldie, watching a humpback whale breach the ocean waves, hunting for bugs at the pond, and the little surprises she brings just because. But when GiGi starts walking more slowly and her visits become quieter, Jack feels the ache of things changing and wonders if their special time together will disappear.

With gentle encouragement from the people he loves, Jack discovers something remarkable: he can be the one to bring the adventure to her. A box of sand and seashells becomes a day at the beach. A jar of caterpillars becomes a miracle they share together.

Jack and Grandma Goldie is a luminous, warm-hearted picture book about the bonds between children and the older loved ones who shape them, and the profound ways children can show up with love, creativity, and courage when it matters most.
