Is it a book...or an electronic tablet? From bestselling author and Caldecott honoree Patrick McDonnell comes a timely tale in a tablet-shaped package that's perfect for today's legions of device-obsessed, digital-savvy children. Here is a hilarious (and heartfelt) 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, digitally-inspired package and design cleverly evokes the experience of using an electronic device that eventually shuts down...and after a magic page turn, Tek reconnects with the real world.
