Bek Trent works for the MASO, an organization tasked with maintaining the tenuous balance between magic users and the rest of society. Silver Alurian is an ordinary high school girl with no idea magic exists. When the two inevitably meet, they find themselves sucked into the twisted plot of the demonic beasts of shadow known as the Zara.
The deepwood is a place without equal, liable as much to give life as to claw it back from those who dare trespass. From within its reaches, a wolf finds herself drawn to mankind. Her curiosity might well undermine her mission; to determine whether the kings of beasts, the dragons, might once again return.
As secrets and schemes collide, new adventures await. And at the heart of them all lies a mysterious, forgotten castle in the hollow heart of the trees. The beasts call it The Castle of Divides.
