I haven't recommended the following book, until now, due to it being political and involving current USA politics.
My idea is this, (and hopefully the mods will agree), to also post this book on a new thread in Hangar Talk where discourse has more leeway.
This thread has value, and it would be a shame for it to be closed due to a book rec that might bring out strong opinions, be they pro or con.
Hence, my thought being, if someone wishes to comment beyond "yeah, good book" or 'it sucks, don't bother" they can go to hangar talk and expound away.
