Rachel's Holiday: Marian Keyes

Meet Rachel Walsh.

She's been living it up in New York City, spending her nights talking her way into glamorous parties before heading home in the early hours to her adoring boyfriend, Luke.

But her sensible older sister showing up and sending her off to actual rehab wasn't quite part of her plan.

She's only agreed to her incarceration because she's heard that rehab is wall-to-wall jacuzzis, spa treatments and celebrities going cold turkey - plus it's about time she had a holiday.

Saying goodbye to fun and freedom will be hard - and losing the man who might just be the love of her life will be even harder.

But will hitting rock bottom help Rachel learn to love herself, at last?
