The Rise and Fall of D.O.D.O. by Neal Stephenson and Nicole Galland
Tristan Lyons recruits Boston linguist Melisande Stokes for a top secret government project, translating modern and ancient documents. Their research shows that magic did exist, but abruptly stopped in 1851. Mel gets absorbed into D.O.D.O. (so secretive that it’s months before she learns she works for the Department of Diachronic Operations) as the pair work with physicist Frank Oda and his wife Rebecca to build an ODEC. At first, the office memos and messages are just something to get through between Melisande’s diary and action scenes. As the pace picks up, the messages get funnier and wilder as the improbable becomes mundane, even as the acronyms pile up. The ODEC is a time travel machine that can only be operated by a witch, and the person sent through time by the witch arrives empty handed and naked. Melisande tries repeatedly to acquire a rare book to help fund their work, Tristan learns to fence, an Irish witch plots to stop the end of magic, Vikings plunder Wal-Mart, and Melisande gets stuck in Victorian London, close to the ending of magic. A complicated, mostly entertaining, and lengthy tale that blends technology, history, and fantasy, along with a good dose of humor.
