When Tash, daughter of a Russian oligarch, is sent to an English boarding school, she is new to the strange rituals of the girls there. Theirs is a world of strict pecking orders, eating disorders and Instagram angst.

While she spends her time with the other girls at the lake and the stables, a hand-picked few are invited to join the Headmaster at his house for extra lessons. Then her friend Bianca mysteriously vanishes, and quickly the routines of her dorm-mates seem darker and more alien than ever before.

Oligarchy is the fierce new novel about power, privilege and peer pressure from the bestselling author of The End of Mr. Y.
