In a mysterious town hidden in our collective subconscious there's a department store that sells dreams. Day and night, visitors both human and animal shuffle in to purchase their latest adventure. Each floor specializes in a specific type of dream: childhood memories, food dreams, ice skating, dreams of stardom.

Flying dreams are almost always sold out. Some seek dreams of loved ones who have died. For Penny, an enthusiastic new hire, working at the store is the opportunity of a lifetime.

As she uncovers the workings of this whimsical world, she bonds with a cast of unforgettable characters, including DallerGut, the flamboyant and wise owner, Babynap Rockabye, a famous dream designer, Maxim, a nightmare producer, and the many customers who dream to heal, dream to grow, and dream to flourish.
