That this book would have been less likely without a certain English princess is beyond dispute. Even Charles Spencer won't deny the influence famous sister had in keeping the family image prominent in both the public eye and the marketplace, whether that means books or Althorp guided tours. Yet he avoids capitalizing on Diana's name, and in the process creates a lively history of a powerful family in an age when, as Spencer writes, "the aristocracy ... is most often perceived as an anachronism." The Spencers first came to the fore in the 15th and 16th centuries. Prosperous Northamptonshire sheep farmers who spun wool into gold, their influence in both politics and the military grew steadily until no Cabinet was complete without a Spencer. Their family tree in subsequent centuries featured a few common themes, including patronage of the arts, a liberal Whig sensibility, books and bookmakers, and sons who chose between the ecclesiastical cloth and the gaming cloth. But they were perhaps most interesting for their women, strong-willed, resolute characters like Sarah Marlborough, Lavinia Spencer, and Georgiana, Duchess of Devonshire. While the Spencer men held power, their wives wielded it. And what of the most famous female Spencer of all, Diana? The author wisely deals with her in less than a paragraph, aware of the glut of words already used up on her life. Unfortunately such discipline doesn't extend to the publishers, who include a picture of her on the book's cover and say that its contents put her life into "vivid context." This is to do an injustice to her brother's cause, for his mix of historical research and family legends makes for a readable account in its own right, enlivened rather than spoiled by his engaging and distinctively Spencerian voice. --David Vincent
