The Avenger — P.C. Cast

For Alexandra Patton, the Time Raiders project sends the reluctant psychic back to 60 AD Briton -- a world where she can barely understand the accents, let alone its culture of brutality and superstition. Armed only with her "freakish" ability to talk to the dead, Alex must use all her gifts to entice Caradoc, a savagely sexy Druid warrior, into helping her succeed in her mission.

What they discover along the way is pure passion.

Now, torn between duty and the man of her dreams, should Alex return home if given the chance? Or dare she risk everything to begin anew in this strange and mystical land?
