As You Desire by Connie Brockway

Kidnapped, drugged, and about to be sold to the highest bidder, Desdemona Carlisle is having a hell of a time maintaining her English pride. Then she sees the man in black, galloping through the Egyptian desert on a pure white steed. Desdemona could not have conjured a more dashing savior in her wildest fantasies. But an unlikelier hero would be impossible to find: Harry Braxton is a rogue, a scoundrel, and a born opportunist—who has already broken Desdemona’s heart once before.

As brilliant as she is beautiful, Desdemona still hasn’t learned how to stay out of trouble—which suits Harry just fine. Running from a painful past, and rumored to be involved in nefarious endeavors, Harry will never be a proper match for Desdemona. But when she catches the eye of his cousin, the irritatingly honorable Lord Blake Ravenscroft, Harry vows to claim his one true desire, once and for all.

The Other Guy’s Bride by Connie Brockway

Determined to prove her worth as a budding archeologist, Ginesse Braxton vows to solve one of the world's greatest mysteries--to find the location of the lost city of Zerzura. Unfortunately, no man dares take the risk of escorting the resolute young scholar across the open desert. But on her way to Egypt, Ginesse engages in a daring deception--she will switch places with Mildred Whimpelhall, who is traveling to meet her fiancé.

Cynical adventurer Jim Owen will do anything to escape the dark secrets of his troubled past. Betrayed by the woman he loved, scorned by proper society, he agrees to carry out a danger-fraught task: escort Mildred Whimpelhall across a lawless desert to her intended. But Jim is about to learn that "Mildred" isn't exactly what she seems . . . and the dangers they face together are eclipsed only by an even greater peril: falling in love, against all reason, with another guy's bride . . .
