Looks like today is Tom Clancy day at Kindle US, with 13 of 15 titles in the Daily Deal being various Clancy titles at $4.99 each. Mostly these are normally pretty expensive, but, per eReaderIQ, several have gone on sale very briefly - and rarely - in the past for $1.99, so up to you as to whether you want to bite at $4.99.
Personally, I really liked the early Clancy titles (
Hunt for Red October,
Red Storm Rising - my favorite, several of the early Jack Ryan books), but once Clancy started putting a lot more of his personal politics, with which I seriously disagree, in his books, I was done.
However, YMMV, and so here's the link for the Daily Deal:
