It’s always hard to say goodbye to a friend. With dazzling undersea pictures and a text full of heart and wit, Charles Fuge and Jane Clarke capture that sad feeling perfectly—and offer plenty of comfort, too.

Ever since Gilbert the Great White Shark was a tiny pup, Raymond the Remora stuck to him like glue. Then, one day, Gilbert’s friend moves away. Nothing can console Gilbert—until he meets Rita, a disconsolate remora who has lost her shark. "I'd love to stick around with you," she smiles, as sunlight dances in her eyes. And that is the start of a beautiful new friendship.
