Gilbert Hernandez, co-creator of Love & Rockets and one of the best American cartoonists — not to mention storytellers — working today, is back with a new book, Bumperhead, a companion to Marble Season. Hernandez’s latest follows a young, slightly bumpy-headed Bobby through childhood, then into his teen years, his experiments with different subcultures, music, drugs, women, and friendships, his grown-up disaffected ponderings, all the way to old age. The book’s storytelling style is frantic, with episodes lasting only a few pages before moving on to something else, no transition — which is somehow exactly fitting. It reads like how memory feels: you get it in snatches, in patterns, in moments of glory or pain. Except Hernandez’s vision is in rather better focus. Bumperhead hits shelves September 16.
