"Boston, present day. A young man from a shadowy government agency shows up at an Ivy League university and offers an eminent professor a lot of money to study a trove of recently discovered old documents. The only condition: the professor must sign an NDA that would preclude him from publishing his findings, should they be significant. The professor refuses and tells the young man to get lost. On his way out, he bumps into a young woman--a low-on-the-totem-pole adjunct faculty member who's more than happy to sign the NDA and earn a few bucks. The documents, if authentic, are earth-shaking: they prove that magic actually existed and was practiced for much of human history. But its effectiveness began to wane around the time of the scientific revolution and the Age of Enlightenment; it stopped working altogether in 1851 at the time of the Great Exhibition at the Crystal Palace in London. It's not entirely clear why, but it appears that something about the modern world "jams" the "frequencies" used by magic. And so the shadowy government agency--the Department of Diachronic Operations, or DODO--gets cracking on its real mission: to develop a device that is shielded from whatever it is that interferes with magic and thus send Diachronic Operatives back in time to meddle with history"-- Provided by publisher.
