Mo Moore, estranged daughter of a sex-aid entrepreneur, regards her father as good as dead. And then he really does die and leaves her all his wealth. Stuck in a job in elderly care, newly single, and with nothing and no-one to keep her in England, Mo does what she's always done when things get tough: she runs.

It could have been anywhere, but a classified ad catches Mo's eye, and it takes her to China. She lands in Pingdi, a remote mountain village that for centuries supplied dildos to the Imperial bedchamber, and whose revived sex-aid factory is in a financial fix. Soon Mo finds herself on the wrong side of the authorities and needing all the help she can get: China is a land of pointing fingers and blind eyes, of closed doors and open secrets, of rules and recklessness - a place, she discovers, where it's not easy to be female.
