Seasons quartet. Book 3 - Sadie Matthews

The third book in the SEASONS series by the author of the AFTER DARK trilogy - a provocatively thrilling and romantic story of desire, submission and love.
All Summer Hammond has ever wanted is love and security. Now, she feels terribly alone. Her sisters Freya and Flora are consumed with their love affairs, and worse than that, their father has finally lost patience with his wayward daughters, deciding he will cut them off financially for good.
The shock of rejection hits Summer hard and she decamps to LA, where she meets Jack Fiori, a gorgeous Italian American. The attraction between them is unmistakable and when Jack invites Summer on a trip to Vegas, just the two of them, she eagerly accepts. But it soon becomes clear that the trip was a ruse. To her horror, Summer realises she's been kidnapped. But Jack won't listen to her explain she's no longer an heiress. For a kidnapper, he seems curiously uninterested in money.
Summer is sure that Jack isn't going to hurt her, but she needs to find out why this is happening. Gradually, the intensity between them builds to levels neither of them can resist. And Summer will find out the secret of why Jack has brought her here and what he hopes to gain...
