Jaine Diamond’s “Hot Mess” is a seductive, dreamy tale about a second-chance romance with a twist. It has a humiliating tattoo, a damaged but alluring bad guy, a misplaced identity, and the lady who is meant to be his. A rock singer named Danny, a breakup party, and a broken heart set the scene for the story. When fate puts them together once more, they might just get it right this time.
