Lance Parkin has written many books about Doctor Who, both fiction and nonfiction. These include "The Dying Days", (much sought after by collectors, having sold out of its print run before the official release date), the BBC's 35th-anniversary novel "The Infinity Doctors", the best-selling "Gallifrey Chronicles", and the new-series novel "The Eyeless". He is also the creator and co-author of "AHistory", a giant timeline of "Doctor Who"that has been in print for nearly 20 years.
