The Alchemist.
The Graffeo book was helpful in the April 2014 exam also. It's a good supplement to some of the other references. I took in the Grainger/Stevenson book but did not need it. I actually ordered the Wildi book after I took the April exam. The explanations are very clear and if I had not passed I do think it would have been helpful. Awhile back another forum member listed relevant chapters. Worth searching for that. No need to plow through the entire book.
