Stick and Rudder is very "un-math" and is a laymen oriented approach to aerodynamics. If the "(insert activity) for Dummies" publishers had been around when it was written, it may have been called "Flying for Dummies". It would definately be a good one to check out. Its a classic, has been used to explain aerodynamics for over 50 years, and can be found for a reasonable price at almost any bookstore.
