The Gibson Vaughn Series

Matthew FitzSimmons, an American boy from Illinois, grew up in London in the 1970s under the baleful eye of the Kings Road punks. His otherwise idyllic childhood was shattered by the traumatic experience of seeing Star Wars on December 27, 1977 in Leicester Square, listening to his father sleep through what was clearly the greatest cinematic achievement of all time, and fearing he was adopted.
