Adrienne Young’s “Sky in the Deep” is a gripping story of long-standing rivalries, fearsome fighters, and surprising partnerships. Raised as a warrior seventeen-year-old Eelyn battles the Riki clan with her Aska clansmen. Her world collapses, though, when she sees the unthinkable a brother she believed to be dead engaged in combat with the enemy. As she struggles to survive the winter with the Riki, Eelyn is forced to consider love, family, and loyalty. This book blends heart and adventure into its pages in a Wonder Woman and Vikings kind of way.
