A new book about love and friendship by New York Times bestselling author and creator of Steven Universe, Rebecca Sugar. When Gems fuse, their forms combine to create a Gem that is bigger, stronger, and more powerful than they are apart. But more importantly, Fusion is a process built on love, trust, and communication. It's like a dance that is perfectly in sync, or a conversation filled with perfect understanding. Learn all about Fusion with Steven, Garnet, Amethyst, Pearl, and the rest of the Gems on Earth as they share what Fusion--and love--mean to them.
