After all, this is Gossip Girl.

In picturesque Rosewood, Pennsylvania, neighbors gossip over picket fences, and gleaming SUVs sit in every crushed-granite driveway. But recently, friendly smiles have been replaced with suspicious glares and accusatory whispers—and it's all because Hanna, Aria, Emily, and Spencer just can't keep their mouths shut.

HRH Princess Samantha has always been a royal rebel. She's the spare not the heir, so no one minds too much who she dates or how hard she parties. It helps that her sister, Princess Beatrice, is literally perfect. She's demure, sweet and beautiful, and she knows that the crown always comes first - no matter what her heart might really want. But they're not the only ones with their eye on the throne. Daphne Deighton might be 'newly noble' but she won Prince Jefferson's heart once, and she'll do anything to get back into the court's favour - and his bed.

Pay close attention, and you might solve this. On Monday afternoon five students at Bayview High walk into detention. Bronwyn, the brain, is Yale-bound and never breaks a rule. Addy, the beauty, is the picture-perfect homecoming princess. Nate, the criminal, is already on probation for dealing. Cooper, the athlete, is the all-star baseball pitcher. And Simon, the outcast, is the creator of Bayview High's notorious gossip app. Only Simon never makes it out of that classroom. Before the end of detention, Simon's dead.

Beatrice Washington now rules America as its first ever queen, but her family is more concerned about rushing through her arranged marriage to a man she barely knows. Meanwhile, Princess Samantha is under more scrutiny than ever before - and she still longs to be with her sister's fiancee. Nina Gonzalez is also tangled up with someone she never expected to be. Luckily for Daphne Deighton, Prince Jeff's grief for his father makes him a prime target for her attentions. As the royal wedding of the century creeps ever closer, will these four young women get what they want?
