A set of lies

From the Publishers:
 
In July 1999 Carolyn and her husband Colin were in a restaurant in Plymouth with a map and a portrait of Napoleon Bonaparte on the wall beside their table. As they waited to be served they began to outline the plot of a book.
 
The more they talked about the idea the more work was required; research, travel to soak up the atmosphere of particular places, reading about those characters who play their role in the plot and who existed. (Though there is no suggestion that they actually did what they are said to have done in this book which is a work of fiction!)
 
The plot has been revisited many times since then. Carolyn had written and published five books since that dinner but now, with the bi-centenary of the battle of Waterloo looming, it is time to bring A Set of Lies to the head of the queue.
 
What's it about?
'History is a set of lies agreed upon' Napoleon Bonaparte.
Has the accepted history of the past two hundred years of English history really been 'a set of lies agreed upon' by the politicians of the day?
A storm leads to a discovery that puts a large question mark over the traditionally accepted events of 19th century history.
Skye Lacey, the illegitimate daughter of a prominent right-wing politician, realises that if she can prove her suspicions true she can sabotage her father's extreme plans for the future of Great Britain.
With two unlikely collaborators, and through an exploration of the lives of six generations of the Lacey family, Skye discovers evidence that proves an unlikely hypothesis and makes the events of two centuries ago impact on the world of today.
