As we prepare for a series of 2021 retrospectives looking at the highs and lows of the year, the bests and the worsts, Darts and Letters is embracing the chaos, looking to the printed word, and scouring the stacks to find the dumbest books that found their way to print. We did not have to look far. In fact, the hard part was choosing from a bursting cornucopia of awful. In the spirit of the new year, this week we feature a roundtable with three guests and two call-in friends, each of whom makes the case as to why their book is the dumbest of 2021.
