“Choosing a book is so gratifying, it’s worth dragging out the process, starting even before finishing the current one. As the final chapters approach, you can pile up the possibilities like a stack of travel brochures. You can lay out three books and let them linger overnight before making a final decision in the morning. You can Google the reviews; ask other people if they’ve read it, collect information. The choice may ultimately depend on the mood and the moment. ‘You have to read a book at the right time for you,’ Lessing also said, ‘and I am sure this cannot be insisted on too often, for it is the key to the enjoyment of literature.”
