Time tornadoes are ripping people from the present, never to return them, while a woolly mammoth inexplicably appears on banks of the River Thames. Eleven-year-old Silver and her guardian live in a house called Tanglewreck, which is somehow at the center of these mysterious time warps. A strange heirloom called the Timekeeper is hidden somewhere in the house, and Silver must find it and protect it . . . because whoever gets hold of the Timekeeper will have the power to control time-and life as we know it-forever. Reviews The sheer exhilaration of the adventure and the many fascinating historical and scientific allusions will keep readers engrossed through to the satisfying conclusion. -Publishers Weekly An appealing read for fantasy and science- fiction fans alike...Well-developed main characters add liveliness and suspense to the story, while secondary characters (a pair of inept thugs, the original Schr�dinger's cat) add touches of humor to a basically sober story. The climax is chaotic and exciting; the resolution is realistic, bittersweet. -Kirkus Reviews Winterson masterfully weaves together an imaginative array of settings and characters to bring the story to its exhilarating fulfillment. Silver's varied relationships add even more depth, encapsulating family, friendship, deceit, and abuse... [T]his time-bending sci-fi adventure will be a fine addition to young adult collections. -School Library Journal Winterson seamlessly combines rousing adventure with time warps, quantum physics, and a few wonderfully hapless flunkies. Her clever science will draw fans of Madeline L'Engle's A Wrinkle in Time, and her dastardly villains and resourceful youngsters will remind readers of the Lemony Snicket's books about the hapless Baudelaires. --Booklist Silver is a plucky hero in the mold of Neil Gaiman's Coraline and Philip Pullman's Lyra, a creature of action not introspection.

    Dreaming that the real world could be a little more like the countless science-fiction books, movies, and videogames he’s spent his life consuming. Dreaming that one day, some fantastic, world-altering event will shatter the monotony of his humdrum existence and whisk him off on some grand space-faring adventure. But hey, there’s nothing wrong with a little escapism, right? After all, Zack tells himself, he knows the difference between fantasy and reality. He knows that here in the real world, aimless teenage gamers with anger issues don’t get chosen to save the universe. And then he sees the flying saucer. Even stranger, the alien ship he’s staring at is straight out of the videogame he plays every night, a hugely popular online flight simulator called Armada—in which gamers just happen to be protecting the earth from alien invaders. No, Zack hasn’t lost his mind. As impossible as it seems, what he’s seeing is all too real. And his skills—as well as those of millions of gamers across the world—are going to be needed to save the earth from what’s about to befall it. It’s Zack’s chance, at last, to play the hero. But even through the terror and exhilaration, he can’t help thinking back to all those science-fiction stories he grew up with, and wondering: Doesn’t something about this scenario seem a little…familiar? At once gleefully embracing and brilliantly subverting science-fiction conventions as only Ernest Cline could, Armada is a rollicking, surprising thriller, a classic coming of age adventure, and an alien invasion tale like nothing you’ve ever read before—one whose every page is infused with the pop-culture savvy that has helped make Ready Player One a phenomenon.
