Decorated FDNY firefighter, 9/11 survivor, and expert emergency manager Tim Brown shares the lessons he's learned about grief, resilience, sacrificial love, and transforming pain into purpose. How do you keep getting up after the worst day of your life?

Tim Brown was on the ground at the World Trade Center during the terrorist attacks that took the lives of nearly 100 of his friends and colleagues—and chose to dedicate his life to honoring their sacrifice. The Greatest Love invites readers to learn from his story, offering timeless lessons on rising from the rubble of our worst days and living a life of sacrificial service. Principles such as "Find Your Sacrificial Why," "Do the Job In Front of You," "Refuse Isolation" and "Cling to Grace" will powerfully resonate with first responders, as well as anyone facing hardship or trying to live from a place of purpose.

Choosing to live by the "greater love" isn't always about sacrificing your life, rather it's about choosing service over self, others over ease, love over fear—even when your heart is broken, especially when your soul feels hollow. With hard-won wisdom, Brown shows how to grieve without being consumed, how to serve when you feel broken, how to leave a legacy for the next generation, how to never forget the sacrifices made by others, and how to live again with purpose. The Greatest Love illustrates the power of sacrificial love—the only force strong enough to transform pain into purpose and hope.
