A Turn of Light (Night's Edge)

The village of Marrowdell is an isolated pioneer community, but it is also the place where two worlds overlap, and at the turn of light--sunset--the world of magic known as the Verge can briefly be seen.

Jenn Nalynn belongs to both Verge and Marrowdell, but even she doesn't know how special she is--or that her invisible friend Wisp is actually a dragon sent to guard her... and keep her from leaving the valley. But Jenn longs to see the world, and thinking that a husband will help her reach this goal, she decides to create one using spells. Of course, everything goes awry, and suddenly her "invisible friend" has been transformed into a man. But he is not the only newcomer to Marrowdell, and far from the most dangerous of those who are suddenly finding their way to the valley...
