2016: Hannah Miller has begun her senior year at The Prescott Academy of New York alongside the rich and famous of the Upper East Side. Or at least, their children.
Among the trust funds and penthouse parties, there’s one rule for survival: staying out of the way of Queen Bees Madison DuPont and Elle Harrington.
Being a scholarship student makes Hannah feel invisible. But no one escapes the watchful eye of notorious gossip account the Upper Edge.
2026: The Academy’s alumni have gathered for a glittering charity gala. Only Madison DuPont could host an event this grand. But what starts as a champagne-fueled party soon descends into chaos when Madison is found dead moments after her speech. It doesn’t take long for fingers to point at Hannah – everyone saw her talking to Madison only moments before she died. She shouldn’t even be at the gala. She’s not really one of them.
The truth is that everyone had a reason to want Madison dead. From Madison’s best friend to her former devotees to the targets of her bullying, it seems like everyone had a complicated history with the Queen Bee of Park Avenue. To clear her name, Hannah must unearth the secrets that this crowd would kill to keep buried.
Gossip on the Upper East Side isn’t just vicious…it’s deadly.
– XOXO
Deliciously scandalous and impossible to put down, Murder on the Upper East Side serves up a deadly amount of drama. With all the addictive gossip, glamour, and messy betrayals of Gossip Girl, this murder mystery will keep you guessing until the very last page.
Gigi Waldorf’s new novel is pitched as Gossip Girl meets Only Murders in the Building, which is all I need to want to read this immediately.
