In the past six years, Riley Sager has published seven novels — all of them best sellers except his first, “Final Girls,” which won a 2018 International Thriller Writers Award. The Pennsylvania native reliably produces one book a year on a strict schedule that sounded remarkably uncomplicated (if dizzying) when he described it in a phone interview. “I usually start on Jan. 2 and keep writing until June,” Sager said. Thankfully for those of us who see the similarities between writing and having a cavity filled, Sager admitted that his seventh book did not go according to plan. “I always have some impostor syndrome going on at all times, but in the case of ‘The Only One Left,’ it just got so complicated narratively that I was lost and in the weeds.”
