A collection that includes the Nebula Award–winning titular novella and “Light and Shadow,” the story that begins the Saga of the Skolian Empire series. In “The Spacetime Pool,” recent MIT grad Janelle Aulair is hiking through the Great Smoky Mountains when a man appears out of nowhere to request her help. Shaken by his impossible appearance, she steps away—and falls through a portal onto a beach in another universe. That’s when Dominick, the man who waylaid Janelle, reveals she is part of a prophecy. It foretells a bizarre future: if Dominick marries Janelle, he’ll depose his twin brother and become Emperor of the land. If Dominick doesn’t marry her, his brother—a brutal tyrant who will do anything to keep his throne—will murder him. Janelle finds herself caught in a conflict that could destroy the realm. If that’s not mind-blowing enough, she discovers books that prove this civilization achieved interstellar travel five centuries ago. Yet now they’re living in a culture that doesn’t have electricity, riding two-horned creatures that definitely aren’t horses, and sword-fighting. To find her way home, Janelle must figure out what happened between then and now . . . The Spacetime Pool also includes Catherine Asaro’s first-ever published story, “Light and Shadow,” featuring Kelric, a popular character from the Saga of the Skolian Empire series, and an illustrated essay on the math in her fiction titled “A Poetry of Angles and Dreams.” Praise for Catherine Asaro “Readers seeking the harmonious meld of hard SF’s rigor and human chemistry’s heat should read Catherine Asaro’s fiction.” —SciFi Weekly
