Suck by Nikki Belaire

This mob boss always gets what he wants – even if she belongs to someone else.
Reece Diavolo. They call him The Devil behind his back, and when the vicious mobster sees the bride at his cousin’s wedding he decides there won’t be a marriage after all that day…because now she belongs to him.
Macy Shaw. They call her The Mouse to her face, and when the goodest of good girls learns her blackmailing fiancé has disappeared she’s relieved…until she realizes her savior is even more dangerous than the groom.
