Going the Distance by Christina Jones
Chaotic, likeable Maddy Beckett lives in Milton St John, where horses, trainers and jockeys outnumber the rest of the inhabitants. Fully recovered from a disastrous love affair and running a successful small business, she is her own woman - until she meets deliciously tall, dark and wealthy Drew Fitzgerald. All is going swimmingly well until his cool and impossibly elegant wife appears on the scene. Maddy desperately wants drew - but does she want him enough to become the other woman in his life?
