Following Fate by Megs Pritchard

Elliot Young had watched his mate from afar, ensuring he and his family remained safe but also making sure they never met. Until they accidentally bump into one another and his mate realised Elliot has lied to him for years.
Alvin Small couldn’t believe it when he finally met his mate. The happiness he felt was short-lived when Eli confirmed he’d known they were mates, but they were never going to mate. Devastated, Alvin decides he will find a man who will love him and his family.
The thought of Alvin being with another man forces Eli to take a deep look at his life and make a decision that will change the course of both their lives.
With danger coming at them from all angles, lives will be lost. Can Eli save his mate before a new threat takes him away forever?
