Anderson's Intro to flight is joy to read and is good intro, he explains things well and you will understand it. The best about it is that he deduce most of the formulas in there, you will really get idea where and with what limitations the laws comes from. There is some few typos in formulas, like missing indexes etc, but really few.

Model aircraft aerodynamics by Simons is good also- there is some lack of formulas but very good qualitative discussion, especially about difference with high and low Re number flow. Low Re are not mentioned in Anderson and i quess in most other full size books.

Andy Lennon is pure application with barely any discussion, a must for reference but not really for understanding.
