Well, for me, I've never liked Eden Gray's books, although some beginners do. To me,they seem deceptively simple, as if they're too dumbed down.
Another one is Eileen Connolly-her books give out weird interpertations on some cards, and has rhymes to remember that seemed to me to confuse you instead. Also, she is very dogmatic, whereas I don't always beleive you have to actually write down some question before a reading.
I like Pollack's books, and a good one just to read up on various interpertations in Louis' books. Reading a variety of authors gave me new perpectives, and it's good to see how other people view it, even if I didn't happen to agree with them....
