What is the best aerobatics book that covers from the beginning level
to the advanced level?

If you can find a copy, then Neil Williams's 'Aerobatics' (Airlife) will
probably lack nothing for most aspiring aerobatic pilots. There may be
more up to date books, but the basics do not appear to change.

Cheers,

Dave
