I tucked my hands into the pockets of my cardigan and pulled it around me in a hug as I set out for my walk. The sun was low in the west, the air nippy. I wandered into Central Square just as the City Hall clock above me struck seven. Crossing the street, past the noisy tavern on the left of the sidewalk, and people enjoying conversations and dinner al fresco on the right, I arrived at Rodney’s. The bookstore is an institution in Cambridge, MA. It sells used and rare books with a fast-changing inventory. I made a beeline for the New to Rodney’s table in the center of the store.
