Looks like an interesting read. Although I could quibble about a fair amount in just that short description (George III "maintained" Pitt in office... good lord). Reading it makes me wonder whether it is going to recycle all the 19th century Whig myths that have been so thoroughly rubbished by modern biographers of Fox and Pitt, particularly Michael Duffy and L.G. Mitchell. But blurbs don't always reflect the content accurately, so I will approach it with an open mind :)
