Thirty years ago, a scholarship boy went up the hill to Ambrose Academy and never came back down. They called it a hiking accident. His great-niece knows better.
Margot Fenn arrives at the three-hundred-year-old academy carrying her great-uncle Toby's battered suitcase and a single purpose: to learn what really happened to him. Because Toby didn't just die at Ambrose. He died six weeks after he pledged himself to Vellum House - the oldest, most secret, and most powerful of the school's societies. The one nobody talks about. The one that still decides who matters here.
To find the truth, Margot has to do the one thing she swore she never would: rush the House. She has to make them want her. And the deeper she goes, the clearer it becomes that Vellum House is not a dusty club of legacy kids playing at secrets. It is a machine, still running, trading in the one thing a school like Ambrose will always have to sell - and the people who built it, the people who buried her great-uncle, never left.
The only person who sees what she is really doing is August, a House insider with a secret of his own. Trusting him could get her the truth. It could also get her killed.
Some doors were sealed for a reason. Margot Fenn is going to open every one.
Vellum House is a standalone young adult dark academia mystery - a secret society, a thirty-year-old lie, an old school full of new danger, and a girl who refuses to look away.
