Holden's favourite book, if I recall correctly, is Don Quixote... but instead of seeing it as a satire of sixteenth century Spain and chivalric tradition he sees the antics of the evidently senile and deranged protagonist as a manual of how to act.

The whole series is Holden tilting at windmills.

They're quite well written and engaging windmills, though, and there's a lot of great Sancho Panzas to accompany and provide a contrast to our knight errand, so it's still a great series.
