Point In Time — Linda O. Johnston

As a successful Hollywood executive, Mariah is on the lookout for the perfect screenplay, and while scouting locations in Pittsburgh, she thinks she has it. With an old-fashioned setting and Thorn, a hero to die for, she knows it will make a great movie. But something will have to be done about the ending--Thorn is too great a character to die. Then a visit to a historic park sent Mariah back in time--to frontier Fort Pitt, where she is rescued by a very real Thorn.
