Dark Romance (Heroine beaten, suicide attempt, interogated)

I've posted this before on other forums with no luck but I'll try again here. It's a really dark novel that I read a few years ago and can't for the life of me seem to find. It's definitely contemporary but the details I can remember are fuzzy.... It might even be part of a series but anyways here's what I remember.... The heroine is being held against her will by the hero and his men, it's suspected that she's either a rat or that she's given up information I think and when they find out they turn on her...I can't remember if she was taken because of this or if she was already amongst them when they found out but they start interrogating her violently to get her to confess I think and the hero even contemplates killing her at one point. I believe he even beats her himself at one point or maybe tortures her in some other way (again it's a dark as hell novel haha) One of his men ends up beating her and maybe trying to rape her? And in that moment she breaks and tries to kill herself.The hero finds her,beats his man to death and saves the heroine from her suicide attempt. After that I remember nothing. Honestly I'm not even sure if what I remember is accurate it's kind of fragmented but any help would be appreciated.
