Parker's first two books were about World War II. ''The Battle of Britain, July–October 1940: An Oral History of Britain's Finest Hour
was published in 2000, and Monte Cassino: The Story of the Hardest-Fought Battle in World War II
came out in 2003. Of the latter, Publishers Weekly'' said: "Parker details, with the aid of hundreds of survivor interviews and war diaries, the Allied siege of the monastery at Monte Cassino, a mountainous fiefdom massively fortified....With command and ground-level detail that buffs will savor, Parker goes over what seems like every inch of the multinational force's campaign." His book
Panama Fever: The Epic Story of One of the Greatest Human Achievements of All Time-- the Building of the Panama Canal (retitled ''Hell's Gorge: The Battle to Build the Panama Canal
for the UK paperback edition) came out in 2007. Allan Massie reviewed it for The Telegraph'': "His narrative is compelling, his ability to weave a pattern from the topics he has to cover quite remarkable...There isn't a dull page, and if this book isn't a candidate for all the non-fiction prizes going, I shall be disappointed." In 2011, he published
The Sugar Barons: Family, Corruption, Empire and War in the West Indies. It was named a Book of the Year by
The Economist and
John Gimlette of
The Spectator called it "compelling, wonderful history. The Sugar Barons is an exemplary book; history as it should be written." Parker next turned to biography, with an account of the life of
James Bond author
Ian Fleming during his years living in Jamaica, titled ''Goldeneye: Where Bond Was Born: Ian Fleming's Jamaica'' (2014). It was nominated for an
Edgar Award in 2016. In 2015, his first look at a period of history before the modern era was published. ''Willoughbyland: England's Lost Colony'' is the story of
Lord Willoughby's short-lived 17th-century colony in what is now
Suriname. John Gimlette reviewed it for
The Spectator: "A miniature masterpiece...this is a truly extraordinary tale and, in Parker's hands, it's beautifully told. With great wit and scholarship he reveals — just for a moment — a cruel and curious world, before it vanishes again beneath the trees." == Personal life ==
