ROSEMOUNT, Minn. - Lt. Col. Mark Weber was told time's up months ago when he was diagnosed with Stage 4 gastrointestinal cancer.
The run now might be even shorter.
"I'm on my fourth chemo trial. There isn't an endless number of chemo to try," Mark said from his home Thanksgiving night.
So in the past several months, the buckets are falling off of his list.
In June, Mark sang a duet with his oldest son for a packed house on the Army's birthday celebration.
Later this summer, he was retired from service in the Army by the Chairman of the Joint Chiefs of Staff, General Martin Dempsey.
And now he has left a piece of permanent parenting for his sons.
"It's essentially nine long letters to them and they are framed in morals," Mark said of his book to be out in December, Tell My Sons.
The book was self published in just eight weeks and it is Mark's way to do just what the title suggests for his boys Josh, Noah and Matthew for every day they face without him there.
"It's hard to read even paragraphs without tearing up," Matthew said of his father's book.
What Mark is leaving in these pages is what he just can't get to when time is short.
But it isn't a sad story. It's actually just the opposite, because he wants his legacy to be his life, not, what led him to his death.
"To focus not on what is lost or not getting what we want but what do we do about what we have," Mark said.
