I really liked the early Tom Clancy books, including
Hunt for Red October and
Red Storm Rising, before he started letting his politics bleed a lot into his books, as he did in some of his later titles.
Red Storm Rising is probably my favorite of his books, to the extent that I've re-read it several times, which is rare for me with a "thriller". Although this reads more like an wargame-ish "history" of a possible WW III than a thriller...
Anyway,
Red Storm Rising is on sale today for $2.99 as part of the US Kindle Dailly Deal, matched at Kobo US.
