The Tugboat and the Silver Moon - Kersten Hamilton

A timeless picture book from the creator of the Red Truck and Friends series about a ship stuck in a canal and the moon that set it free.The silver moon sails through the vast blue sky as a cargo ship down below is stuck in a canal. The tugboat tugs until the line goes taut. The diggers scoop up enough sand for a castle. The dredger glugs all the silt he can. But it's no use. For seven long days, the moon watches as the ship stays put, becoming fuller, brighter, closer, until she's finally strong enough to pull the ocean into a mighty tide and save the ship.
