Allow me to begin by saying I’m no numerologist. I do believe, however, that one day, we will all understand why the numbers in our lives intermingle and coordinate the way they do. I also believe that this overlap of figures is more than just mathematical. There is a purpose to the numbers, and it’s not just coincidental.

Here’s a good example: I was born on July 5. As a kid, I lived on Fifth Street. My stepdad was born March 5. My oldest son was born January 5. My best friend growing up had a birthday 25 days later than mine. Many of my other family members have birthdays, anniversaries, and other important dates that are influenced by the number five — maybe they’re multiples or maybe the dates add up to something five-related. Perhaps that last bit is stretching the significance a little, but you get the picture.

So I suppose it shouldn’t have surprised me when, the other day, my publisher emailed to tell me that my latest book, Hard Inheritance, had been published on the date of my grandfather’s death 12 years prior — December 5th.

To really grasp the importance of this chronological lineup, you have to know the kind of influence my grandfather had in my life. As a young child, I grew up on his citrus farm in Hardee County, a very rural community in southern central Florida. My grandfather loved me more deeply than almost any other person in my life, save my mother. He invested his time, his resources, and his wisdom in preparing me to become a hard working, honest, and thinking man.

He had flown 51 missions in World War II, and his American devotion carried well beyond his military service. He served his church as a deacon (a model I would later follow myself). He faithfully worked for the Coca-Cola Foods Division as a groves manager for decades before retiring to volunteer with my scout troop. I became an Eagle Scout because he taught me the value of persistence and perseverance; seeing a thing through to its successful end.

It only made sense to me when Hard Inheritance came out on the fifth. Of course it would, I thought, following the five-laden trail of bread crumbs throughout my life. It’s both fitting and bittersweet that this book, my best and most earnest to date, would become available to the public on a day with such meaning.

My hope now is that this volume would please him, were he still here. It celebrates the beautiful and the natural, but it also shows the events in life that leave our scars and calluses, both of which he was intensely familiar with. It celebrates Our Florida — that place that he, six generations of our ancestors, and now my children call home.

I think he’d like the history, the honesty, and the geography of this book. He’d probably laugh at the pieces he’s featured in, having forgotten an episode that seemed relatively unimportant to him, but one in which I find deeper relevance. He, too, was a “five” man, after all — born in the month of May, living to the age of 83 (subtract the two digits), and being great-grandfather to five children (3 girls by my sister, 2 boys that are mine).

Being connected to one particular number in such a vital way can sometimes be a Hard Inheritance  of its own. Rarely a day goes by when some important connection to the number 5 doesn’t crop up in my day-to-day life. Were I one to play the lottery, I sometimes think I’d buy one of those “Pick 5” tickets and just play all fives to see what happens. My statistician friends would discourage this, of course, knowing the wild improbability of winning from such a choice.

But if it’s one thing that my life has taught me, it’s that all the cold, sterile math in the world can’t explain the way that numbers work. There is no algebra, no geometry, no trigonometry or physics formula to rationalize how the figures align. And in that same logically inexplicable space, poetry lives.

Tomorrow will mark five days since my book was published. I will celebrate by watching my oldest son, number 35 on his basketball team, play his final game of the season. I will think of how proud my grandfather would be — both of my writing and my boys’ achievements. I will hope for more fives in the future. And I know that I will surely receive them.
