Blood's Not Thicker

Mila's life was already far from normal. She had been raised with eleven other teens to become the best trained agents for their country. On their very first mission she discovers through a somewhat clumsy maid that she is the true heir to the crown she is protecting. She runs from her new life to protect those she loves, but when faced with the reality of the situation she has no choice but to go and take back what is her's.
