Which books should I get by Tom McEvoy and Ken Warren, if any?

[KSOT]

I notice they've written a lot about the game, which I can only assume means their books are successful sellers. I've read almost every poker book 2+2 has published and am ready to move on to other perspectives.

Can people who have read their work recommend their better books? It doesn't matter what aspect of poker they're about, as long as they're not introductory.

Thanks.
