The Cairo Effect (Tempus Fugitives Trilogy #2)

Ella Stevens is a woman on the eve of her wedding when a frantic phone call from an old college pal sets her on a course that takes her away from the altar and away from any semblance of life as she knows it. Unfortunately, rescuing her friend means losing herself when she stumbles onto a time portal in Old Cairo that sends her back in time at the moment just before the greatest archaeological discovery of the age. Trying desperately to get back to her own time and her fiancé, a sexy US Marshal who—contrary to popular belief doesn’t have all the patience in the world—Ella discovers that evil isn’t limited to any one timeline. With the startling discovery of the most precious treasure she will ever have, Ella risks her life to protect it while fighting to find her way back to her man.
