Phantom by Fiona Davenport

Kian “Phantom” Weber spent fifteen years working in the shadows to protect his country. The retired spook found his family with the Silver Saints MC…and they eventually led him to the woman who was meant to be his.
When Phantom spotted the bruises on Tessa McGuire’s arm, he knew he would burn down the world to ensure her safety. With him at her side, anyone who wanted to hurt Tessa would have a battle on their hands. Because he knew in an instant that he’d have her back. Always.
