I am receiving an Amazon gift certificate which I am NOT allowed to spend on school textbooks.
Thus, I'm spending it on a CP book. I already have Peter D'Amato's and Barry Rice's books, so I'm looking for a suggestion for a third book. I am leaning towards Schnell's book, but I would also like to solicit suggestions.
If you were to add a third book to your CP library, which would it be?
