The Daddy Clause by J S Grey

The only thing that Will Fisher wished for this Christmas was for his son Silas to be happy in their new home.
Being a newly divorced single dad of a six-year-old can be tough enough, but finding yourself back on your home shores for the first time in years is even tougher. Determined to make this Christmas special, Will takes Silas to see Santa in the pop-up Santa’s magical kingdom that all of London is raving about.
Will gets more than he bargained for when he comes face-to-face with Niko Calus. Santas are supposed to be fat and jolly right? Why is this muscled mystery man making him so hot under the collar this cold winter season? Especially since Will Fisher is straight.
Niko Calus wants everything Will Fisher has to offer, but there is one problem. Niko has a secret, one that could change the world forever. Caught between his obligations to the family business and the inferno of desire ignited by Will, Niko must make a life-altering decision that had far-reaching consequences.
Can Will find happiness back home? Or will his past come back to make this Christmas not so merry?

Christmas is Coming.
You better watch out!
