Just a few weeks ago, I was sitting around the house, looking for something to read to get my mind off of things, and I decided I wanted Terry Hayes’ “I Am Pilgrim,” a thriller from 2014 about a terrorist planning to release a horrible virus upon the United States. The problem was that our local bookstores — including our own Printed Page — were closed following the governor’s “stay-at-home-and-read” order, so I went online to order it.
