Heart of a Fighter by Max Hudson

Ever since the day his parents died, Niall has had one aim in his life—taking care of his family. For him, that means doing whatever it takes to make sure that his kid sister doesn’t starve, freeze, or get pushed into a life of prostitution by the no-good uncle who gained custody of the siblings.

Rising through the ranks of street fighters and eventually becoming a legitimate businessman, he has kept his word and provided his sister with a comfortable life far from the nightmare of their childhood. Between work and his sister, he can’t imagine that there is anything missing from his life. That is until he finds himself face to face with a new recruit whose secrets may threaten to ruin the peaceful life he’s worked so hard to build.

Adrian knows who he is and what he wants. In Niall Peak, he sees all the things he’s ever yearned for but never thought he could have. When the hunky owner of a private security firm begins to strong arm his way into his life, Adrian must decide whether or not he is willing to take the risk and love again.
