Apparently, the novel was reworked for its 2008 re-release, eliminating some of the glaring differences between its original 80s publication and today. I haven't read the newer version, but I did just read the second sequel, White House Autumn, and I am working my way through the third, Long Live the Queen, which are both the reworked versions of their original 80s and 90s publications.
I thoroughly enjoy them, because they're good at humanizing the official position. Even in the day of constant Twitter updates (or maybe because of them), I think we forget that politicians are people with families who are heavily impacted by the political lifestyle. While not perfect (they can sometimes get a little repetitive and characters can be excessively goody-goody), these books do a great job of guestimating what it's like to be in the shoes of a President's daughter.
But those covers...they are hideous. Highly reminiscent of those weird 90s covers with people striking weird poses.
