I have tried and failed to read Neal Stephenson many times over... However, I do enjoy a good time-travel story, especially if there are witches involved (Diana Gabaldon or Deborah Harkness, anyone?). This met both of these requirements, and then some! The book focuses on time travel (from a witchcraft perspective) but under the guise of being a tool of a shadow branch of the NSA. That, combined with a terrific cast of historical events and their characters (American and European) made this an unputdownable read. I most sincerely hope that this is the first of a series, and have resolved to redouble my efforts to read other Stephenson novels. Highly, highly recommend.
A discreet translation assignment enmeshes a linguistics expert and a military intelligence operator in the world-shattering revelation that magic was once widely practiced and can be reactivated if they travel back in time to make historical changes that are complicated by human treachery. 150,000 first printing.
