What aspects of the authors’ previous works captivated your enjoyment? Personally, my three chosen authors are Nicholas Sparks, as we all crave romance in our lives; Rick Riordan, whose books rekindle the youthful enthusiasm within me; and lastly, Fredrik Backman, whom I consider the finest realistic fiction author.
I would pick three authors I’ve never read before and read all their stuff. Then I’d switch completely to movies and tv series. Reading the same things more than three or so times doesn’t appeal to me.
