Passion's Promise - Danielle Steel

Smart, beautiful, and very rich, Kezia Saint Martin leads two lives: one as a glamorous socialite jetting between the poshest places in Europe and America; the other, under a false name, as a dedicated journalist committed to justice and her profession.

But the two worlds are pulling her apart, leaving her conflicted about her identity and the lies she tells to every man she meets. Then she meets Lucas Johns, a bold, dynamic crusader for social change -- and an ex-con. Their attraction is immediate, but their love may be just one step from tragedy at any time.
