I agree this is a great book. However, I would put it further down in your list as it is almost a carbon copy of stick and rudder. They touch in a few different points, but for the most part all the same stuff. I read them back to back in a 10 day span.

Here are some more for your list:

For intro aero/good safety info on engine failures: Emergency Maneuver Training by Rich Stowell

For in depth aerodynamics, but still laymen terms: The Illustrated Guide to Aerodynamics by H. C. "Skip" Smith

For a more technical aerodynamics book, designed for pilots not engineers: Aerodynamics for Naval Aviators

For human factors in pilot error: The Killing Zone by Paul A. Craig & Pilot Error by Phaedra Hise

For accident report studies, a wonderful way to gain insight on your own short commings as a pilot (we all have them): Aircraf Safety Accident Investigations, Analysis & Applications Second Edition by Shari Stamford Krause, Ph. D.

To study flight discipline: Flight Discipline by Tony Kern

Random insights on flight instruction, including various lessons for any pilots: The Flight Instructor's Manual Fourth Edition by William K. Kershner

To study radios, but also keep it short and sweet (this book takes maybe 2 days to read and has tons of info): Say Again, Please Guide to Radio Communications Third Edition by Bob Gardner

Weather flying, IMO a must have/read for every pilot: Weather Flying Fourth Edition by Robert N. Buck (Buck flew into 100s of thunderstorms in the 60s, if I remember my timeline right, to study their effect on aircraft. It is weather information few pilots in the world can speak about.)

One more book on weather, micro meteorology mostly (this was written by a glider pilot): Understanding The Sky by Dennis Pagen

Finally take a look at the some of the oxford aviation training text books. I particularly like the one on navigation. These books are written for European curriculums. The Europeans have a unique way of explaining various forms of navigation and I personally prefer their style to the American counterpart. This book is titled Navigation and is part of the ground training series. It is book number 3 in their line of training.
