A turn of light

"The pastoral valley of Marrowdell is home to a small pioneer settlement of refugees, lush fields of grain, enigmatic house toads -- and Jenn Nalynn, the miller's daughter. Life here is full of laughter and peace, as well as hard work, and no one bothers overmuch about the outside world. Except Jenn Nalynn. ... Long ago, a cataclysm of misused power pinned Marrowdell to the Verge, a place of wild magic, home to dragons and even stranger creatures. Should Jenn step beyond Marrowdell, she will pull the worlds asunder. ... But time is running out. What Jenn unknowingly feels is the rise of the Verge's magic within her, a magic that will threaten her and those she loves."--Page 4 of cover.
