這本書的中間有一道牆。牆的左邊有個小小騎士，而牆的右邊呢……不知道，但聽說有很可怕的食人魔。所以小小騎士很慶幸，有一道牆保護他所在的這一邊。可是另一邊真的充滿危險嗎？這一邊又真的是安全的嗎？有一天，當意想不到的事發生，小小騎士發現，好像並不是這麼回事……FROM中文簡介

Sunday Times Culture Magazine Book of the Week;There's a wall in the middle of the book, and our hero-a young knight-is sure that the wall protects his side of the book from the dangers of the other side-like an angry tiger and giant rhino, and worst of all, an ogre who would gobble him up in a second! But our knight doesn't seem to notice the crocodile and growing sea of water that are emerging on his side. When he's almost over his head and calling for help, who will come to his rescue? An individual who isn't as dangerous as the knight thought-from a side of the book that might just have some positive things to offer after all! Jon Agee is brilliant in his use of the page turn, visual storytelling, and deadpan humour, and appeals to fans of Oliver Jeffers and Jon Klassen.
