Beast, Part II by Ella James is the second book in her four-part serial Beast. 
 So this book begins with Annabelle straightening her clothes after being animalisticly ravaged by Ricardo/Cal/Beast. Beast offers her the deal of granting a one day reprieve for Holt (the step-father and warden) for every day she visits Beast. She is to be at his beck and call. She tells him she needs a job, she has to make money to take care of her ailing mother and her 4-year old sister. He offers to pay her. She's taken home and given time to think about the offer. She also spends a lot of time thinking about Beast. 
 She gets a call from Holt telling her things are fine and she doesn't need to go back to La Rosa Prison. Just then a man named Clinton shows up at her house to collect her and take her to Beast. They are in the library that is under construction. When she meets beast again he shows her the new balance of her bank account. She has issues being paid for sex. She's not a whore - he disagrees, she's his whore. She still believes he doesn't remember who she is from the night of the accident and party, but he does. 
 "Angel... My Angel. I remembered you. Of course I did."~ Beast 
 Beast has bosses. It's how he's been able to essentially run the prison from the inside. He has a job to take care of tonight, he has to murder another inmate. It's early morning (3 am-ish) and the job is done and he calls Clinton to bring Annabelle to him. They talk and reveal some secrets in his cell, but then something goes wrong. Is the immunity Beast has earned from his bosses being ripped away or is someone else after him?
