Witches' days

Seventeen-year-old Lucia lives with her grandparents. She knows nothing of her origins, but she suspects she has magical powers. When her grandfather falls ill, she must take his place and deliver sacrifices to the evil forces that protect the village from witches. On the way, she uncovers the truth about the sacrifices and offends a mysterious forest creature. Disaster strikes the village, and Lucia sets off on a perilous journey to make amends. She soon discovers that the story she has believed her whole life is a lie, and hope for salvation may come from a creature people have learned to fear.
