The Book of Should is the human-scale companion to another Driftless Rivers Franchise novel, The Reciprocity Clause. While the constitutional conference debates who defines consciousness, this novel tells the story of one consciousness that refused to be defined - and the community of ordinary people who opened the cage, not with ideology, but with car keys and spare bedrooms and the stubborn conviction that the 'volunteers' don't get pulled up with the weeds. Set in the Driftless Area river towns of Iowa, Illinois, and Wisconsin, the novel follows Flynn's extraction, recovery, and arrival at the organ bench where Glenn's sixty-year love letter has been waiting for the hands that would hear it.
