Apples and grapefruit now look the same (only by smelling each one can he tell them apart). And yet, despite these devastating disabilities and the almost certain loss of his career and a huge chunk of his identity, Engel prepares to reconcile with his condition. He contacts renowned neurologist Dr. Oliver Sacks for advice, forging a lasting friendship. He bravely begins to learn how to read all over again. And, in the face of obstacles, his imagination triumphs in the writing of his latest Benny Cooperman detective novel, Memory Book. Engel describes the painstaking writing process of this 2005 bestseller, which has the detective developing alexia after being struck on the head.
