Dark Blade

Lann knows nothing of his mysterious past, but by his fifteenth birthday he will come face to face with destiny. For Lann must wield the Dreadblade, an ancient sword forged to defeat terrible monsters.
Across the mountains a King has been murdered. His daughter, Astrid, is a warrior with no desire to bear the crown. Only she can uncover her father’s killer before her brother is framed for the crime.
Evil is stirring. Lann and Astrid are the kingdom’s last defence. Together, they must face the greatest darkness their world has ever known.
