The day that Coach Daniel Kane had to identify the gruesome remains of his eight-year-old granddaughter, he became radicalized. Marnie McKay was murdered by an AR-15 in her third-grade classroom. Her death required retribution, and those responsible for legalizing the sale of weapons of war to the public would now have their own offspring in the cross-hairs of an unlikely cell of determined assassins. NOT ONE MORE is the primal scream of millions of Americans repulsed by the frequency of mass shootings. The book explores the heartache of loss, the journey to healing, and the moral struggle to overcome a primal and deadly impulse for retribution.
