The envelope sat in my rural mailbox right on top of a circular for farm equipment and a utility bill for $138.42. It wasn’t addressed to me in the usual way with my full name typed out by some machine at a bank. It was handwritten in neat, sloping blue ink that looked entirely unfamiliar, yet it had that unmistakable curve to the capital letters that made my chest tighten before I even flipped it over. The return address was printed in small, crisp letters at the top left corner. Porter & Vance Medical Group, Iowa City. Dr. Hannah Porter.
