The Time Keeper is the story of Father Time, how he came to be and how he came out of his curse. Dor was both a genius and a fool for measuring something as abstract as time. He was a genius in the sense that he was able to create logic between days and he was a fool because something as inanimate and intangible as time was what he measured.
Mitch Albom is the master of these kinds of novels. It was able to teach without being preachy. It makes you want to continue reading on and on until you have finished the book. It was a tear jerker too.
It does present the importance of the present moment. There is no other time that is as important as the present moment. I recommend that you read this book!
