A Reluctant Melody - Barnes Brothers, #2

Romance. Secrets. Second Chances. Kit Barnes' drinking ruined more lives than his own. Now sober, he wants to make amends by opening a mission for drunkards. The most suitable location belongs to Joanna Cranston Stewart, a love from his sordid past and the one person he hurt the most. A pariah among her peers, Joanna is all too eager to sell her property and flee the rumors that she sent her late husband to an early grave.
But she will let the gossips talk and the walls of her rundown property crumble around her before she'll allow Kit back into her life. When a blackmailer threatens to reveal her long-held secret, she must choose between trusting Kit or seeing her best friend trapped in an abusive marriage. Will Joanna risk another betrayal? Or will she find a way through the pain of the past to love and trust again? (Originally released in 2016.)
