If you had one hour to live and could make just one phone call, who would you call? What would you say?

Why are you waiting?

Richard Carlson's sudden, tragic death in December 2006 left his millions of fans reeling, but even their many letters, calls, and emails couldn't erase the loss felt by his wife Kristine.

To try and come to terms with her loss, she pored over 25 years of love letters, reliving the memories and cherishing her late husband's memory.

But one letter stood out. Richard had written to his wife on their 18th wedding anniversary and attempted to answer the question: if you had one hour to live, what would you do, who would you call, and what would you say?

An Hour to Love is a profoundly moving book that shows the importance of treasuring each day as the incredible gift it is.
