The Fourth Edition of Ahistory, the definitive timeline to Doctor Who, incorporates nearly 2,500 Doctor Who-related stories (the TV show, the books, the audios, the spin-off series, the everything) onto a single timeline, from the beginning of the Universe to the end of time. Volume 2 (of 3) of Fourth Edition encompasses the Present Day, UNIT, Modern Day (through 2017) and Gallifrey sections of this astonishing work, which collectively is more than a million words of hardcore Doctor Who analysis.
