Point By Point: a 1920s historical fantasy romance

More to the point, Lydia can't keep going as she has. There's never enough money, nor enough time. She's always scrambling, never sure of the ground beneath her or whether she can rely on anyone for help. The last year has brought too much change. His parents are rightfully under house arrest, and Galen and his brother are setting up new lives. Restoring the family business after it was nearly run into the ground by a serious of bad decisions is only the first problem. When Lydia asks help investigating the aftermath of an odd news story, Galen is intrigued. So are his friends in the secret society Galen has been part of since his school years. The investigation begins with a horse race, but it soon leads them from the clubs to a decadent house party to a far more dangerous gathering that could change everyone's life forever.
