Heart in the Clouds — Joy St. Clair

On a call-out, helicopter pilot Jillane Talbot finds that her passenger is none other than her estranged husband, the ruthless but devilishly handsome, Ash Carey. Jillane had run out on him five years earlier, and thought it best to regard their marriage as having ended. However, Ash has different ideas, and when he discovers an unbelievable secret that she has kept from him all these years, he vows to win her back.
