The greatest 'can you find it' book ever wasn't technologically possible until now. Using MagicView, a proprietary technology for hiding and revealing images in print, readers of The Spirit Glass must follow the clues that appear in this book to know where—and how—to place the Spirit Glass decoder to bring unseen images to light. In thirteen imaginative spreads, readers will find ten ghosts in a haunted house, seek out nine skeletons hidden in a graveyard, uncover hidden messages in invisible spider webs and much, much more!
