From a beloved, bestselling Caldecott Honor recipient comes a hilarious reminder of how technology can take us backward... all the way to the times of prehistoric man! § Tek is a cave boy in love with tech: his tablet, videogames, phone, and TV keep him deep in his cave, glued to his devices, day in and day out. He never sees his friends or family anymore--and his ability to communicate has devolved to just one word: "UGH"! Can anyone in the village convince Tek to unplug and come outside into the big, beautiful world? § A distinctive package and design cleverly evokes the experience of using an electronic device that eventually shuts down... and after a magic page turn, Tek (and the reader) reconnects with the real world.
