Pastry Chefs: Baking Book?

Hi! I really want to go to pastry school after finishing undergrad and I wanted to get a professional/textbook type baking book so I can start learning now! Any suggestions? I have looked at Wayne Gisslen's Professional Baking and I am really liking that one. I have also seen The Professional Pastry Chef by Bo Friberg and the CIA Baking and Pastry. I don't really want a book that only has recipes that make huge quantities of food but I also don't want a regular cookbook. Any tips you have would be greatly appreciated :)
