Until everything goes pearshaped and she finds herself being frogmarched to the Cloisters - Dublins answer to the Betty Ford Clinic. Shes outraged. Surely shes not thin enough to be an addict? But on the bright side, shes heard that rehab places are wall-to-wall jucuzzis, gymnasiums and rock stars going tepid turkey. Besides, its about time she had a little holiday.

Rachel isnt expecting plump, middle-aged men in brown jumpers, and more group therapy than you can shake a stick at. That - alarmingly - she seems to be expected to join in with. Who cares for introspection when all there is to look at is damaged and broken?

Heartsick and Luke-sick, she seeks redemption in the shape of Chris, a Man with a Past. A man who might be more trouble than hes worth.

Rachel is airlifted from addiction to the unfamiliar terrain of adulthood, via a love story or two, in a novel by turns poignant, powerful and seriously funny.
