Ten years ago, in Lee Child's Echo Burning, Reacher was recruited to kill a stranger. Now, Otto and Michael Flint race to find the executioner who refuses to relinquish his ill-gotten legacy. Filled with twists and turns to keep you breathless until the explosive finale, can Otto and Reacher work together to stop the heinous assassins before it’s too late?"-- Amazon.com
