Yesterday, today and always... Now that Dr. Kasey Harris is part of the team, the Worlds Together aid unit is complete and ready for their assignment. The only problem is, the head of the team is gorgeous, arrogant surgeon Adam Chandler – and Adam and Kasey have met before.... Once deeply in love with her, Adam has never quite forgotten Kasey – nor forgiven her for ending their affair. As they work together under intense pressure, Kasey begins to realise that throwing away his love was the worst mistake of her life. Now, if they can put the past behind them, they could be together...forever.
