Follow the Timecachers on a chase through colonial Boston For the last year, the Timecachers have been fulltime field test engineers of the LANav, a revolutionary navigational device capable of navigating through both space and time. When a malevolent engineer from a rival company steals one of the devices and accidentally transports himself to 1770, Adam, Sal, Alice, and Tom must follow him through a series of time beacons, taking them on a chase through the tumultuous and rebellious days of colonial Boston. Armed with nothing more than the exhaustive notes of the pre-revolutionary period from their knowledgeable historian, they try to apprehend the thief before he can alter history, while braving dangerous events such as the Boston Massacre, the Boston Tea Party, and the first battle of the American Revolution at Lexington
