How far will four friends go for immortality? This novel is Hugo and Nebula Award–winning author “Robert Silverberg at his very best” (George R. R. Martin). After Eli, a scholarly college student, finds and translates an ancient manuscript called The Book of Skulls, he and his friends embark on a cross-country trip to Arizona in search of a legendary monastery where they hope to find the secret of immortality. On the journey with Eli, there’s Timothy, an upper-class WASP with a trust fund and a solid sense of entitlement; Ned, a cynical poet and alienated gay man; and Oliver, a Kansas farm boy who escaped his rural origins and now wants to escape death. If they can find the House of Skulls where immortal monks allegedly reside, they’ll undergo a rigorous initiation. But do those eight grinning skulls mean the joke will be on them? For a sacrifice will be required. Two must die so that two may live forever . . . Stretching the boundary between science fiction and horror, Robert Silverberg masterfully probes deeper existential questions of morality, brotherhood, and self-determined destiny in what Harlan Ellison refers to as “one of my favorite nightmare novels.” This ebook features an illustrated biography of Robert Silverberg including rare images from the author’s personal collection.

“A ribald, Byzantine tale of time-tourism” from the multiple Nebula and Hugo Award–winning author (Tor.com). It’s 2059, and former law clerk Jud Elliott finds himself at loose ends—until a chance meeting with a Time Courier gives him the inspiration to become one himself. The job—as a time-traveling guide—gives him the opportunity to indulge his love of Byzantine history, in between shuttling tourists to such monumental events as the crucifixion and the assassination of JFK. But there are strict rules to follow as a Time Courier, put in place to guard against paradoxes and preserve the sanctity of “now-time.” Jud isn’t used to following the rules—especially when faced with temptation. All it takes is one tiny slip here, one misplaced step there, and Jud could destroy his own timeline and cease to exist in the blink of an eye . . . a practicality that’s hard for Jud to grasp when he crosses paths with an eleventh-century Byzantium beauty he can’t resist. “A hugely ambitious, enormously fun, sly, paradox-peppered piece that chronicles the time-tourist trade and all its perils—specializing in Byzantine history.” —Strange Horizons “This novel is a comedy, and it is funny, but it is one of those black comedies where things go wrong, and then the more the protagonist tries to fix things, the more wrong they become, until the ending is at one and the same time an O. Henry punchline and a deep existential truth, neat as a pin and just as sharp.” —Kim Stanley Robinson

The Harmonists find the answers to life’s eternal questions in their own spirituality and in their own bodies, which have undergone genetic changes on Venus, giving them paranormal abilities.
