Hustle by Maya R. Stone

Hustle
Gabriel Harrison is the Kings of Justice’s Sergeant at Arms. A former soldier, he is committed to his MC club safety and his biker brothers’ well-being. He loves his lonely life, and he doesn’t indulge in the most decadent sides of the MC lifestyle. Although he’s a bachelor, discipline and structure rule his life.
His routine will collapse when Mason, VP of the Dark Knights, an allied club of the Kings, brings his sister, Ava, to the clubhouse. Ava needs protection, and Hustle is the only one available for the task.

Ava
She thought she accomplished her dreams when she got married to a successful attorney five years ago. But it was a huge mistake. Now, she’s on the run, and her only hope is her brother, Mason. When she thinks she’s safe with him, a riot in the heart of the Dark Knights, his brother’s MC, puts a new target on her.
Her only hope? Apparently, a ripped and stoic enforcer from another club, the Kings of Justice. A handsome, badass biker who talks little and barks commands.
He says he will protect her. He promised her brother he will. He tells himself she is only another task. The sexy brunette is just another person to protect and take care of. Then why can’t he stop thinking about her?
She wants a new life. Freedom. Independence. She doesn’t need a man telling her what to do. Then why can’t she avoid looking at him?
A woman who is hurt, a strong biker who wants to be her shield. An attorney who wants his wife back and gets a Russian mobster’s help. Lots of action, romance and erotism in this intense story.
