Meet two friends who think they’re building imaginative worlds with blocks but come to realize they’ve been building something far greater—a sturdy, solid friendship—in this picture book by award-winning creators. Two kids build entire worlds out of blocks, cardboard, and imagination, from boats attacked by a sea creature to a castle crumbling into the ocean. And they don’t mind when these creations break apart and CRASH to the floor. In fact, they think it’s pretty funny!

Playful text by wordsmith Minh Lê and dazzling illustrations by artisan Dan Santat showcase their close collaboration in their latest picture book. As merry as it is moving, here is a story that recognizes the friendships in life that are truly built to last.
