Passing through a strange mist, Trevara finds herself in another world where she encounters reptilian carnivores and hostile unicorns. She finds much more when she discovers haven within a mysterious fortress. She meets a young warrior, Garth, who is from her own world, Terra. Together they struggle to survive the perils of their new world. Along the way they meet a sorcerer who claims to have the power to return them to Terra. Trevara and Garth discover a different kind of struggle as they fall in love. A sorcerer of the black arts, and a battle with hideous Trolls separates the two. Returned to Terra, Garth races to find Trevara and her son. A struggle between armies complicates his quest when Trevara is felled by enemy arrows and Mallock is captured. In a race against time and evil, a mysterious sword of power and a fallen star begin an adventure that will produce the first Emerald Knight.
