It will make you laugh, cry deeply, and want to call your siblings’ Cosmopolitan

The Blue sisters have always been exceptional – and exceptionally different.

Avery, a strait-laced lawyer living in London, is the typical eldest daughter, though she’s hiding a secret that could undo her perfect life forever.

Bonnie was a boxer but, following a devastating defeat, she's been working as a bouncer in LA – until a reckless act one night threatens to drive her out of the city.

And Lucky, the rebellious youngest, is a model in Paris whose hard-partying ways are finally catching up with her.

Then there was Nicky, the beloved fourth sister, whose unexpected death left Avery, Bonnie and Lucky reeling.

When, a year later, the three of them must reunite in New York to stop the sale of their childhood home, they find that it's only by returning to each other that they can navigate their grief, addiction and heartbreak and learn to fall in love with life again.
