Thanks for all the feedback. Ordered several of the books suggested last night. Wanted to add a few more (Pepin's Complete Techniques, Notes from a kitchen etc) but they were sold out - will get them at a later point. I was very happy to source 'La Varenne Practique' for only $37 in "as new" condition.
Ended up with these:
The Professional Chef
Flavor Bible: The Essential Guide to Culinary Creativity, Based on the Wisdom of America's Most Imaginative Chefs
Ruhlman's Twenty: 20 Techniques, 200 Recipes, A Cook's Manifesto
La Varenne Practique
In addition I got a few baking cookbooks for my soon-to-be-built wood fired oven.
The Art of Wood-fired Cooking
Wood-Fired Cooking: Techniques and Recipes for the Grill, Backyard Oven, Fireplace, and Campfire
Bread Baker's Apprentice: Mastering the Art of Extraordinary Bread
