Felix by Terry Bolryder

Felix, or Fifi, is finally free of his past. At least the part where he was a dreaded assassin for the ruling class of his society. But his one great regret, his one chance at true love long ago, is lost. Presumed dead. Or so he thought…

Diana is on a mission. Get revenge on the man she once loved. Revenge for a broken past that Fifi can never repent for. But the second they’re together, she immediately gets second thoughts. With love—and passion—as hot as they share, maybe it’s worth taking one last shot.

Fifi can’t believe his mate is back. And this time he intends to protect her, no matter the cost.
