This is Juan's earlier books and the first edition was a rough translation. This is better, but not
perfect. It's good enough to get through it. I believe I have every English book of Juan Tamariz
and I will buy all of his works just to keep his collection updated. With that said, If I didn't
want to own all of his books, I might have skipped this one. It's good, but his newer books are so
much better.
