ISBN 0373190697 - It's okay. It's just not anything more than okay. It's a romance novel, like many, many others. I had high hopes when the author referred to the famous World War II Christmas Truce... but that was on page 19 and it was all pretty standard from there.
Darian and Tom are both busy folks, with busy lives. Tom has a family business and ranch to run and Darian has a law career and a son. Neither of them has time for the usual wooing and winning of love, but they do enjoy each other's company. Jason, Darian's son, is a handful who responds well to Tom and bonds with him from the first. So, why not get married? Tom wants a family, Jason needs a father... and Darian... Darian wants to be a partner. Eventually, they all get what they want, and more!
I did find Jason calling Tom "Dad" after knowing him for all of a couple months to be a little annoying, but other than that, My Dearly Beloved is pretty standard fare.
