Earth’s past and future are altered by twenty-fourth-century time travelers in this “significant work of science fiction” from the author of Arkwright (Rocky Mountain News). Chrononaut Franc Lu has come a long, long way—from the twenty-fourth century, in fact—to be in New Jersey on the evening of May 6, 1937. Traveling four hundred years into the past, he and his partner have been sent by the Chronospace Research Centre to observe the infamous explosion of the zeppelin Hindenburg. But when the German airship touches down safely on the airfield in Lakehurst, Lu realizes that something has gone terribly wrong—or rather, horribly right. His presence at the landing has set in motion an alternate historical timeline, and now everything will be different, though not necessarily in a good way. The consequences of Lu’s mistake could prove catastrophic for every living soul on Earth, now and forever, unless the past and the future are somehow repaired—and that is a burden destined to fall on the shoulders of visionary NASA scientist and wannabe science fiction author Dr. David Zachary Murphy.   An expansion of his Hugo Award–winning novella “ ‘. . . Where Angels Fear to Tread,’ ” Allen Steele’s Time Loves a Hero is at once thrilling, surprising, startling, and thoughtful—a mind-blowing masterwork of speculative fiction that radically reimagines time travel, alien contact, alternate history, and a host of other well-worn science fiction tropes.
