One of the most respected and awarded of all contemporary science-fiction writers, Connie Willis repeatedly amazes her many admiring fans with her ability to create vivid characters in unusual situations. With Doomsday Book, she takes listeners on a thrilling trip through time to discover the things that make us most human.

For Oxford student Kivrin, traveling back to the 14th century is more than the culmination of her studies - it's the chance for a wonderful adventure. For Dunworthy, her mentor, it is cause for intense worry about the thousands of things that could go wrong. When an accident leaves Kivrin trapped in one of the deadliest eras in human history, the two find themselves in equally gripping - and oddly connected - struggles to survive.

Deftly juggling stories from the 14th and 21st centuries, Willis provides thrilling action - as well as an insightful examination of the things that connect human beings to each other.
