The Kings Amulets

When the Vampire King dies, each of the heir must find the Amulet of Kings.

Ashton Ciaran Durand, the youngest of his three brothers is determined to succeed, and keep his brother Sebastian off the throne. But his young appearance, even though he's over 500 years old, makes searching for the Amulet almost impossible. But to be able to come of age needs to form a blood contact.

Juliet Lambert, a junior in high school student, spends most of her time alone. With her father across seas on business and mom leaving her before she could even walk. And with winter break here, she's expecting to spend the entire time locked in the apartment.
One night she finds Ashton injured, and takes him home and even makes a Blood Contract.

Can Juliet help Ashton locate the Kings Amulet before his brothers can?
