If we’re doing older books, David Horowitz’s “Radical Son.” Not only enlightening but entertaining as well because he’s a good storyteller.
I’ll second that. “Radical Son” was a very interesting read, although the first time I attempted to read it it was tough to get through David Horowitz’s academic writing style.
Most political books by O’Reilly, Hannity, and others are written to be easily digested by the public but Horowitz was a bit more challenging for me at the time.
I switched to Mona Charon’s “Useful Idiots” and it provided a good background on historical events that on a second attempt “Radical Son” was a lot easier to read.
He was definitely a liberal who saw the light after seeing the evil. There are definitely parallels to Whittaker Chambers' Witness.
