The two teenagers at the center of “The Future of Us,” a slight but winning young adult novel by Jay Asher (“Thirteen Reasons Why”) and Carolyn Mackler (“The Earth, My Butt, and Other Big Round Things”), do get to peek into their own futures, thanks to a wormhole located in an unlikely place - on the AOL CD-ROM one of them installs on her new desktop computer. What I really wanted was for someone to tell me, in essence: “It’s O.K., Teenage Dan. Perhaps one day my adult self might zip back through the decades for a quick visit to Whitefish Bay High.įuture Dan could tell me how to handle my angry girlfriend and which college I would eventually decide on, and that I should enjoy my full head of hair while I still could. In the darkest days of high school - when I agonized over girls, when I couldn’t decide what to do about college, when I couldn’t find a way to make my bushy hair not look stupid - I often wished that time travel would be invented.
