Doomsday Book Hardcover – June 1, 1992 by Connie Willis 
 
Connie Willis draws upon her understanding of the universalities of human nature to explore the ageless issues of evil, suffering, and the indomitable will of the human spirit.

“A tour de force.”—The New York Times Book Review

For Kivrin, preparing to travel back in time to study one of the deadliest eras in humanity’s history was as simple as receiving inoculations against the diseases of the fourteenth century and inventing an alibi for a woman traveling alone. 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—barely of age herself—finds she has become an unlikely angel of hope during one of history’s darkest hours.
