The first in a YA trilogy, rooted in Russian and Slavic myth, in which each new book is better than the one before. During a terrifying encounter on the magically-created Shadow Fold, quiet and passive Alina discovers her remarkable gift: she is a sun summoner. As she studies with the magical elite, she begins to understand how she has the power to save her kingdom—or ruin it, if her gift falls into the wrong hands. A magical coming-of-age story.
