This is book 8. This is a stand alone romance, and can be read and enjoyed, even if you haven't followed the series. 

Charlie’s plan: Sweep into town, pick up a fake bride, get his inheritance, and leave like the wind after a quickie divorce in Caribbean paradise, untying the knot fast enough to cause whiplash.

 Jaime’s plan: Not to be duped by the charming Casanova, no matter how much he promises to pleasure her with his hotter-than-hot-package. Getting intimate, then signing papers over Piña Coladas and saying adios wasn’t quite her style.

 She wanted the real deal, but the problem with bad boys is that they don’t do commitment. She knew a happily ever after with Charlie was never going to happen.

...unless fate intervened.
