The Viking Assassin Tome 1 (Broché)

Nora Hunt has just joined the deadly quest to discover the ancient legend : the nine worlds of the Vikings. Her post-apocalyptic dystopian world, Triangle of Peace, is the only home she's ever known. But at sixteen years old, the skilled young warrior joins an elite band of raiders called Jarls. Her mission ? Merely to win the perilous battle for the artifacts that awakens the Viking realms and avoid falling in love with the charming boy who just happens to be her worst enemy - and she's not quite sure which task is more difficult.
But when Nora learns the Norse gods bestowed upon her a mystical secret in the form of the tattoo on her back, the stakes are higher than ever to claim the great Viking Empires.
