Now, after a number one hit on iTunes, nearly two million singles sold, live performances where they have shared the stage with Demi Lovato, Shawn Mendes, and Fifth Harmony, and over 26 million followers across all their social media channels, Jack & Jack are on a wild ride—and they’re not planning to slow down anytime soon. Fans will love reading about their journey from being two regular kids growing up in Omaha, Nebraska, to global superstardom. Complete with never-before-seen photos, behind-the-scenes stories, and hilarious personal anecdotes, You Don’t Know Jacks is an insider look at the lives of Jack & Jack, as told by the guys themselves. Gr 9 Up—Back in their high school days, Gilinsky and Johnson created a Vine that they dubbed "Nerd Vandals." The Vine went viral, racking up more than 10 million plays, thus paving their way to social media stardom. Since then, they've become Vine stars, YouTube celebrities, and popular musicians. This book serves as a photo album, providing images from their childhoods through recent concerts, with an extended Q&A in which the pair discuss embarrassing school moments, relationships, and their path to the spotlight. They detail their transition from Nebraska to Los Angeles, their decision to delay college in favor of their entertainment careers, and more. Some of their comments reflect their youth ("I don't want to be single my entire life. That stuff's fun, but once you're past twenty-five, you know what you want") and light misogyny ("I don't think you should ever, on principle, kiss and tell. Unless it's some badass celebrity chick like Rihanna. Then you gotta brag and tell your bros. You just gotta.").
