Ariana Grande captured the hearts of a nation with her One Love Manchester concert.

Less than a fortnight after a terrorist killed twenty-two people at her Manchester show, the petite princess stood tall at her tribute concert that united and healed a shaken nation. She was the emotional core of a powerful evening that reminded us all of music's redemptive power.

But who is Ariana Grande? This candid book traces the US pop star's story from her childhood in Florida, through her teenage years on Broadway and Nickelodeon, and on to her gleaming pop career which has seen her described as "the new Mariah Carey".

This unauthorized biography tells the songbird's eventful and inspirational story in full for the first time, and shows how she became an award-winning, chart-topping pop idol, as well as an empowering inspiration for a generation of girls.

It reveals that there is more to Ariana than the celebrity we all think we know, explaining how her smooth transition from a squeaky-clean teenage pop product to a sophisticated, bold artist was powered by a restless and resilient personality.

This is a full, unflinching portrait of a pop sensation and inspiring, uncompromising woman—the small, sassy girl with the ponytail who conquered the world.
