Cat and Fish come from different worlds — he from the land, she from the sea. But when they meet in the park one night, they like each other's looks. Cat shows Fish his world and teaches her how to climb, how to take shelter from the rain, and how to stay warm. But Fish misses the sea, so Cat takes her back and meets her friends and discovers the water world. Then the trouble starts. Opposites may attract, but can they find common ground and stay friends? Neil Curtis’s stunning black-and-white illustrations make this whimsical story of how two unlikely soul mates overcome their differences spring to life, enchanting young readers and their parents alike.
