"A tour de force" - New York Times Book Review
For Kivrin Engle, preparing an on-site study of one of the deadliest eras in humanity's history was as simple as receiving inoculations against the diseases of the fourteenth century and inventing a bullet-proof backstory. For her instructors in the twenty-first century, it meant painstaking calculations and careful monitoring of the rendezvous location where Kivrin would be received.
But a crisis strangely linking past and future strands Kivrin in a bygone age as her fellows try desperately to rescue her. In a time of superstition and fear, Kivrin finds she has become an unlikely angel of hope during one of history's darkest hours.
Winner of both the 1993 Hugo and Nebula Best Novel awards, this is a science fiction classic.
