No Plan B (Jack Reacher 27) by Lee Child

In Lee Child's "No Plan B," readers are plunged into a gripping tale of suspense and peril alongside the iconic character Jack Reacher.
In Gerrardsville, Colorado, a woman's death under a bus is ruled a suicide, but Jack Reacher witnessed the true events: a stealthy figure in a gray hoodie pushed her before casually taking her purse.
When another death is labeled an accident, Reacher suspects foul play.
Unaware of the larger conspiracy at play involving arson, a runaway foster kid, and powerful figures, Reacher becomes determined to unravel the truth.
Despite underestimation from his adversaries, Reacher's relentless pursuit of justice leaves no room for error. In the face of danger, there's No Plan B when Reacher is on the case.
