“Eifelheim is one of those very occasional novels that you know early on you will never forget. A powerhouse.” –Jack McDevitt

“With a sure grasp of both speculative science and medieval history, Flynn compellingly weaves past and present together in a dialog of faith and science. With neat turns of plot and intriguing medieval and modern characters, this book, parts of which were previously published as a novella, belongs in even small libraries. Highly recommended.” –Library Journal, starred review“Michael Flynn's Eifelheim is a gripping multi-layered masterpiece, which pulls off the extraordinary feat of imagining a convincing first contact with aliens that might have taken place in 1348, and adds an equally convincing account of the manner in which the event might be rediscovered by a 21st-century historian. The intricate detective story is supplemented by a heartfelt moral commentary on the manner in which the contact was negotiated and the crucial significance it retains, in spite of having been forgotten for nearly 700 years.” –Brian Stableford "Eifelheim is a truly impressive and enjoyable novel."Stanley Schmidt
