The Wrong Man by Kitty King

I shouldn’t love her. She’s too young for me…
And I think I killed her father.
Essa is determined to sell her virginity to pay off her debts. An adult film production company outbids all others on her auction. If only the man she’s interested in would volunteer to be her co-star, but Eli has been in prison for the last seven years.
When he is released, he gets an offer he almost can’t refuse: on-camera sex with a girl thirteen years his junior. He must, though. Through his nightmares, Eli remembers being present on the night of Essa’s father’s murder.

Was he the one responsible?
