La Runa Secreta / Viking Magic I: Runestone (Spanish Edition)

Growing up in Viking times, a boy and a girl, Oddo and Thora, both share a similar problem: they don't feel like they belong in their respective families, though cannot imagine why. What they are about to discover is that they were switched at birth—Oddo, the magical child, grew up in a household of farmers, and Thora, the sensible, practical one, grew up amid magical mayhem. Following this timely discovery, the two embark on an adventure in which they must rely on magic, healing powers, and loyalty to one another.
