A postmodern fairy tale might best describe Jacques Roubaud’s delightful book The Princess Hoppy or, The Tale of Labrador. How else to describe a novel that reads like an Arthurian romance as rewritten by Lewis Carroll, with enough math puzzles to keep the game reader busy with a calculator for months?

The tale concerns a princess, her faithful dog (who happens to be a wiz at math), four royal uncles always plotting, four royal aunts always potting, a lovesick hedgehog named Bartleby, two camels named North Dakota and South Dakota, four ducks who double as boats (thus called doats), and an amphibious blue whale named Barbara-to name only a few. (Even the Sun has a speaking role.) There are dramatic abductions, daring rescues, passages in hitherto untranscribed languages (Dog, Grasshopper, Duck), tales of unrequited love, allegorical interludes, poems, a playlet, and much more. (But no suspenders, the author promises.)

Finally, there are 79 questions for readers of the novel, to see how closely they’ve been paying attention-for ultimately The Princess Hoppy is a giddy inquiry into how we read literary works. It is both an old-fashioned tale and an ultramodern hypertext, the oldest and the latest thing in fiction.
