The Singles Game by Lauren Weisberger

New from the author of THE DEVIL WEARS PRADA: it’s a match made in hell.
When Charlotte ‘Charlie’ Silver makes a pact with the devil, infamously brutal tennis coach Todd Feltner, she finds herself catapulted into a world of stylists, private parties and secret dates with Hollywood royalty.
Under Todd it’s no more good-girl attitude: he wants warrior princess Charlie all the way. After all, no-one ever won by being nice.
Celebrity mags and gossip blogs go wild for Charlie, chasing scandal as she jets around the globe. But as the warrior princess’s star rises, both on and off the court, it comes at a high price. Is the real Charlie Silver still inside?
Sweeping from Wimbledon to the Caribbean, from LA to mega yachts in the Med, The Singles Game is a brilliantly entertaining romp through a world where the stakes are high – and no-one plays by the rules.
