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.
