The first time Moth told me he loved me was the first time I’d ever heard those words said. No one had ever said they loved me before, not my parents or friends, no one ever before, and those words had lifted me up, shining, glowing, into the next thirty-two years of my life. But words had no strength against Moth’s brain shifting into self-destruct, against a protein called tau sludging up the cells, blocking the connections.
