Book 17.5 in the Jack Reacher series (2013)
July 1977. Jack Reacher is almost seventeen, and he stops in New York City on the way to visit his brother at West Point. The summer heat is suffocating, the city is bankrupt, and the mad gunman known as Son of Sam is still on the loose.
Reacher meets a woman with a problem, and agrees to help her . . . but then the power grid fails and the lights go out, plunging the lawless city into chaos. What does a visiting teenager do in the dark? If that visiting teenager is Jack Reacher, the answer is plenty.
