Tek: The Modern Cave Boy by Patrick McDonnell
Tek is a cave boy in love with tech: his iPad, 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?
