**The #1 *New York Times* –bestselling author’s “hilarious . . . idiosyncratic . . . delightful” and definitive companion to a global phenomenon ( *Publishers Weekly* ).** Douglas Adams’s “six-part trilogy,” *The Hitchhiker’s Guide to the Galaxy* grew from a blip of a notion into an ever-expanding multimedia universe that amassed an unprecedented cult of followers and became an international sensation. As a young journalist, Neil Gaiman was given complete access to Adams’s life, times, gossip, unpublished outtakes, and files (and became privy to his writing process, insecurities, disillusionments, challenges, and triumphs). The resulting volume illuminates the unique, funny, dramatic, and improbable chronicle of an idea, an incredibly tall man, and a mind-boggling success story. In *Don’t Panic* , Gaiman celebrates everything *Hitchhiker* : the original radio play, the books, comics, video and computer games, films, television series, record albums, stage musicals, one-man shows, the Great One himself, and towels. And as Douglas Adams himself attested: “It’s all absolutely devastatingly true—except the bits that are lies.” Updated several times in the thirty years since its original publication, *Don’t Panic* is available for the first time in digital form. Part biography, part tell-all parody, part pop-culture history, part guide to a guide, *Don’t Panic* “deserves as much cult success as the *Hitchhiker’s* books themselves” ( *Time Out* ).
