Xander by Kaz Crowley

Xander can’t forgive himself for letting Seth get away. Reluctant to put a ring on the eager omega and give him what he truly desired, he broke his true love’s heart and never quite recovered.
Now he’s discovered that Seth is deep into the world of BDSM, and he must brave his fears and step into new waters to win his love back. What he discovers changes his life forever.
Xander doesn’t know that Seth got pregnant all those years ago. Raising his child in another city where he went for a new job, Seth finds that family problems are calling him back to Stell, his little boy in tow.
Seth immediately finds his way to the local BDSM community and makes friends, but when he reconnects with Xander, he has tough decisions to make.
As Seth’s mother’s health continues to deteriorate, and the secret he holds grows bigger and bigger, he realizes he needs to decide whether he can try again with Xander.
And Xander learns that kink is a way to connect with the man he lost—and doesn’t plan to lose ever again.
Especially not when the six-year-old son he never knew he had enters his life.
