Mammoth

When eccentric megabillionaire Howard Christian commissions a hunt for a frozen mammoth in northern Manitoba to clone a new model in Varley's rollicking, bittersweet tale of time travel and ecology, he gets more than he bargained for: next to the 12,000-year-old beast his team unearths lies the body of a human being, wearing a wristwatch, with a metal box—a time machine?—nearby. Christian hires Matt Wright, Canada's top scientist on the physics of time, to fix the machine, and employs elephant vet Susan Morgan to oversee the cloning of a new mammoth. The machine hurls Matt and Susan back to the mammoth age, then forward again, along with a baby Columbian woolly mammoth, Fuzzy, whose engaging story cleverly alternates with Christian's indefatigable quest for personal fame. Varley's sparkling wit pulls one surprise after another out of this unconventional blend of science and social commentary with real people convincingly doing unreal things. Fuzzy, though, is the true hero, an irresistible 15-foot-tall reminder of the wonders of nature and imagination. The winner of numerous Hugo and Nebula awards, Varley (Millennium ) should garner new laurels with this outstanding effort. Agent, Kirby McCauley at the Pimlico Agency. (June 7)
