HIS CHANCE AT REDEMPTION 

Former parole officer Mick Hudson blames himself for the death of Keeley Stevens's sister. If he hadn't paroled a criminal, she might still be alive. When he hears that the suspected killer has been spotted in Keeley's hometown, he worries she might be the next victim. Keeley doesn't want to take help from the man who could have prevented her sister's death, but she has more than herself to worry about. She'll do anything it takes to protect her family. And Mick will risk his life to make sure that the past does not repeat itself.
