Georgette Lawson has always been the dull, practical twin…until she steps foot on the tropical island of Palumba. Desperately searching for her missing sister, Georgette plays a dangerous game that results in whispered threats and dire warnings. One such warning comes from sexy Jake Kincaid, the main developer of the island. Now Georgette’s life…and heart are at risk.

He wants uptight Georgette Lawson to abandon her search for her flighty twin and go home—until the danger to Georgette becomes all too real. His fight to save the island and expose its seamy underbelly becomes an even greater fight to save Georgette and claim her as his own.
