Good Books/Resources for Short Handed?

[SixForty]

Hey all,

I'm a regular small stakes full ring player. I know that there are some specific parts in my game that I need to work on - specifically shorthanded/headsup situations and blind stealing/defense. So I'm thinking of starting to play a fair bit of shorthanded games online in the next little while to work on that.

I was wondering if anyone can steer me towards any good books or other informational resources that are geared specifically towards shorthanded play, or have good shorthanded strategy sections.

Thanks a lot for the help!
