I purchased this textbook and never used it because my professor tricked me into buying books, but he did not once mention or give us an assignment from. I don’t even think I’ve ever opened this book. I purchased it for 45. And will be listing it for 30. I know how text books can be expensive so I tend to discount them The isbn is 9780521001298 Title is on the free choice of the will, on Grace and free choice, and other writings
