Sinner Like Me by Avril Ashton

The mysterious Syren Rua has found love…

Settled into a life of contentment with his marshal and the daughter they’re raising, Syren Rua finally knows happiness. All the pain and dark memories brought him this far and for the first time, he’s lowered his guard to take it all in. Blinded by love, he doesn’t notice the approaching danger until it taps him on the shoulder.
But don’t let that fool you.
He never thought he’d have a family, but Kane Ashby finds one with Syren. Nothing is more sacred. When what he holds most precious is threatened, Kane and the man he loves—along with the rest of their found family—will cross oceans as they fight to protect what matters most.
