Loner. Lawbreaker. Bad girl. These all describe Hannah Tree, but she never expected to add private detective to the list...

Serving a minor prison sentence isn’t the usual training for becoming a private investigator. But Hannah’s new mentor Gloria Starr, a statuesque trans woman, convinces Hannah to turn her obsession with justice into a business.

Hannah’s first case is simple. A routine check on a client’s spouse, a judge whose wife is worried about him. Gloria suspects he might be a member of the mysterious “Friday Night Club”. Everything changes when Hannah sees her father entering the club.

Something sinister is happening that not all the members know about. Determined to uncover the truth, Hannah discovers that some secrets are deadly. But she’s waited her entire life to bring her father to justice, and she’s not going to stop now. Even if it's the last thing she'll do.
