Do you believe the grass is greener on the other side just because your best friend says it is?

A more unlikely pairing you’d struggle to find, but Roxy and Ginny have been there for each other since they were five years old, when Roxy beat up Kevin Smith for putting gum in Ginny's hair.

Although Roxy now lives the high life in London and Ginny is still at home in sleepy Farnham Hills, the bonds of love, respect and eye-rolling irritation still remain.

But after her latest romantic catastrophe, Roxy decides she needs a city de-tox – no more London, no more reception work at high-class brothel, no more decadent night-life and definitely no more men.

Meanwhile, Ginny’s so deep in a rut she needs a pair of Roxy’s thigh-high boots to clamber out.  Dating Andrew for 12 long years and stamping books at the local library, she’s craving a walk on the wild side.

So they swap lives.

For Ginny, it’s a whirl of champagne fuelled- parties and outrageous flings in the lap of luxury. For Roxy, it’s the indignity of man-made fibres and terminal boredom in the library.

And they’re about to discover you get more than aching feet when you walk in your best friend’s shoes…
