This is the hardback equivalent of a tabloid newspaper -" listen as former Secret Service agents dish dirt on the First Families!!!" (For those keeping score at home, Nancy Reagan & Hilary Clinton are battleaxes, the Carters are standoffish & rude [and had the worst kid to protect:], and George H & Barbara Bush come off smelling like roses.)

Another theme of the book is horrible management of the Secret Service - logistics, staffing, preferential treatment, outdated equipment, etc. Since the author acknowledges the cooperation of the Secret Service in preparing the book, I'm guessing that someone in there wanted to send a not-so-subtle message to Congress to beef up their appropriation.

Interesting nuggets about protection training & actual situations (the attempts on Truman & Reagan) are buried in gossip-y schlock.

Finally, the book is essentially unsourced - like I said, tabloid newspaper stuff.
