Secrets, rumours, and dangerous liaisons - at an elite New England boarding school, they come with the territory.

It's move-in day at Tiffin Academy and amidst the happy chaos of friends reuniting, selfies uploading, and cars unloading, shocking news arrives: America Today just ranked Tiffin the number two boarding school in the country. It's a seventeen-spot jump - was there a typo? The dorms are dingy, the sports teams always come last and Tiffin students are known for being more social than academic. But the campus is exquisite, class sizes are small, and the dining hall is run by a New York chef. And they do have lots of fun . . .

But as the rarefied air of Tiffin is suffused with self-congratulation, scandalous bulletins begin to appear on phones across campus, thanks to a new app called Zip Zap, and nobody is safe. From Davi Banerjee, queen bee and international influencer, to Simone Bergeron, the young new history teacher; to Charley Hicks, a transfer student who seems determined not to fit in, it seems everyone has something to hide.

As the year unfolds, bonds are forged and broken, secrets are shared and exposed, and the lives of Tiffin's students and staff are changed forever.
