IMO, Jonathon Little's books are excellent tournament strategies and the ones I've had the most success with so far both online and offline! you can buy all three volumes from
http://www.amazon.com but if you've never signed up to
www.audible.com you can get your first free book which he's narrated, that's what i did anyway.
I'm currently working through Tilt Armour to help with my mindset, I recently discovered this one when looking for good books on poker mindset and tilt control which was really poor at. It's excellent but more of a course than a book. You can get that one from
www.tiltarmour.com
Hope this helps!
