Tartine is a great book that will make you hate every almost perfect loaf that you bake. It's well written and well photographed, though it can be difficult to follow at times. Although Chad goes to an effort to explain how the recipe can adapt to any schedule, it's still a huge amount of effort - you start on Friday night and don't get a loaf until Sunday.

It's also very difficult the first time you work with such high hydration doughs, and I would suggest watching:

Chad on Bon Apetit - to see how he actually does it: https://www.youtube.com/watch?v=U4dyWZZVeWI

Sourdough on It's Alive, good fun and educational: https://www.youtube.com/watch?v=oidnwPIeqsI

I also have the River Cottage Handbook on Bread which I strongly recommend for practical recipes.

Also buy a crock pot or a combo cooker. By far the simplest way to get amazing looking bread.
