Once, in my father's bookshop, I heard a regular customer say that few things leave a deeper mark on a reader than the first book that finds its way into his heart. Those first images, the echo of words we think we have left behind, accompany us throughout our lives and sculpt a palace in our memory to which, sooner or later—no matter how many books we read, how many worlds we discover, or how much we learn or forget—we will return.
