On the eve of their thirtieth birthday, twin brothers Jake and Zack Hind—bankrupt from the recession and obsessed with the lost golden era of the 1990s—drunkenly create a Kickstarter crowdfunding page for '90s ISLAND, a tropical commune dedicated to recreating that beloved, carefree decade. When they wake up, Generation Y has collectively pledged millions of dollars. At first it's a thrilling return to the twentieth century: '90s fashions, '90s music, '90s slang, '90s video games, even '90s junk food…but the fun turns to horror when Zack seizes dictatorial power, banning everything from modern books to medicine. Jake must stop him—but first he must conquer his own nostalgia.
