The Scionless House (The Scion Legacy #0.5)

Twelve Houses. Twelve vampire lines. We ruled from the shadows, and manipulated the world, and when humans came too close to destruction, we intervened.
Every House has a Scion. A fragile, easily broken human that stood shoulder to shoulder with the house Princes and Princesses.
Except for ours. The Ravens, House Cantelie.
We've been without a Scion for almost fifteen years.
But that will change...and her life will be mine to protect.
