Beginning with The Long Road to Mercy, published in 2018, the Atlee Pine series by David Baldacci features the eponymous Atlee Pine as an FBI Agent assigned to the Grand Canyon. But amidst the gruesome murders she solves, Atlee harbors an even darker past – the death of her twin sister, Mercy, after the two girls were kidnapped at just six years old. The series, which continues A Minute to Midnight (2019), Daylight (2020), and Mercy (2021), follows Atlee’s struggle to balance her career with her search for answers about what happened to her sister, why her parents disappeared, and the revelation that not everything about her kidnapping is what it seems. The Florida-Times Union describes the series as “Baldacci at his best.”
