*NATIONAL BESTSELLER* A cancer diagnosis caused Tyler Merritt--beloved author of I Take My Coffee Black--to realize that there was no time for anger, unforgiveness, foolishness, or lost friendships. None of us have any time to waste. When Tyler Merritt was diagnosed with cancer, everything he thought he knew about what mattered in life changed. Though he made it through a highly invasive surgery and thought he was in the clear, Tyler soon realized that the cancer had other plans. It wasn't a question of if the tumor would come back for an encore, his doctors told him. It was a question of when. The clock was ticking. This Changes Everything is a humorous and optimistic love letter to this beautiful life. As Tyler counts down the days until his next scan, he begins to understand that none of us have time for anger, for being unforgiving, for foolishness, for letting relationships drift, or for letting friendships to be lost. It's a clear-eyed reckoning with the reality that our time on this earth is limited and a hopeful vision of how each of us can make the most of the time we have left. Laced with Tyler's trademark humor, love of pop culture, and arguably too many musical theater references, This Changes Everything is a story about how wrestling with the idea of death can birth a whole new outlook on life, how we live it, and the urgency that comes when you grasp that time is a precious commodity.
