'I wish I could get a seat on the tube... I hadn't eaten that entire bag of Maltesers... I could meet a man whose hobbies include washing up and monogamy...'

Heather Hamilton is always wishing for things. Not just big stuff - like world peace or for a date with Brad Pitt - but little, everyday wishes, made without thinking. With her luck, she knows they'll never come true...

Until one day she buys some heather from a gypsy. Suddenly the bad hair days stop; a handsome American answers her ad for a housemate; and she starts seeing James - The Perfect Man who sends her flowers, excels in the bedroom, and isn't afraid to say 'I love you'...

But are these wishes-come-true a blessing or a curse? And is there such a thing as too much foreplay?
