A “rollicking, bittersweet tale of time travel and ecology” from the Nebula and Hugo Award–winning author of the Gaea Trilogy (Publishers Weekly, starred review).   “H. G. Wells meets Jurassic Park” in this novel about a multibillionaire, a time machine, and a baby woolly mammoth named Little Fuzzy (The Best Reviews).   The discovery of a perfectly preserved frozen mammoth in the Canadian wilderness gives wealthy visionary Howard Christian the opportunity of a lifetime: to clone it. But what really piques Christian’s curiosity is what he finds next to the mammoth: a metal box—and the mummified body of a man wearing a watch.   Working to discover the box’s purpose and clone the mammoth, a top physicist and an elephant veterinarian will be flung thousands of years into the past and back again—bringing a baby mammoth along for the ride—in this “imaginative and engaging” adventure that shows “Varley . . . in top form” (San Francisco Chronicle).  Praise for John Varley   “John Varley is the best writer in America.” —Tom Clancy   “There are few writers whose work I love more than John Varley’s, purely love.” —Cory Doctorow   “One of science fiction’s most important writers.” —The Washington Post   “Inventive.” —The New York Times   “One of the genre’s most accomplished storytellers.” —Publishers Weekly
