Dragon Dad’s Mate by Amelia Wilson

Nora has found her family, and she cannot lose them.
After receiving several threats to her life, Nora is seeking answers. She thinks these answers are wrapped up in one student, Ashton. An angry ten-year-old, whose first line of defense is throwing the first punch. There’s something deeper at play, however, and Nora is convinced it starts with Ashton’s dad.
Meeting Cain isn’t difficult… getting him to talk isn’t easy though.
Despite Cain’s roughness, nothing he says deters Nora from trying her hardest to help. As Cain and Nora learn to communicate and cooperate with each other, it’s safe to say Ashton isn’t behind the threats. She is grateful she can ease her suspicions, but it brings back old fears.
Who is behind the threats?
