'A Farewell to Kings'... I could almost have seen that as an alternate title to 'Reap the Whirlwind'... Definitely sounds like a usable title for something in the future, if not this book.
I like that one; even if it might not fit the particular novel, it keeps with the operatic titling of the first three Vanguard books.
Who is Rush, btw? I've only heard of them here and in David Mack's 'about the author' segments.
