Savage Lovers by Ashe Barker

She needed a saviour. What she got was a savage protector.
Jenna is in trouble. She’s borrowed money and borrowed money, all from the wrong kinds of people.
Even worse, her brother’s best friend has come sniffing around, wanting to know why she can’t pay her debts. The only thing more embarrassing than admitting she’s broke is the shameful way her body reacts to Tony’s humiliating discipline.
Now, one of her debtors has come to collect. And the price for not paying up is far steeper than Jenna ever expected.
She came searching for her sister. What she found was a savage family.
All of Ruth’s sources say her sister is in Glasgow, in bed—literally—with the infamous Savage family. Desperate to reconnect with Beth, Ruth breaks into their headquarters.
And finds herself in a holding cell, her bottom sore from the business end of Jack Morgan’s belt, and the rest of her aching for his punishing touch.
The longer she stays in that cell, the more unlikely it seems that she’ll ever see her sister, or any of her family ever again. Because men like Jack don’t have patience for intruders.
