Princess Guinevere has come to Camelot to wed a stranger: the charismatic King Arthur. With magic clawing at the kingdom's borders, the great wizard Merlin conjured a solution - send in Guinevere to be Arthur's wife...and his protector from those who want to see the young king's idyllic city fail. The catch? Guinevere's real name - and her true identity - is a secret. She is a changeling, a girl who has given up everything to protect Camelot.

Sixteen-year-old dock boy Will is on the run, pursued by the men who killed his mother.

But after their father dies suddenly while reading a book Joanna has never seen before, the sisters must reunite to preserve their family legacy.

For Ning, the only thing worse than losing her mother is knowing that it's her own fault.

When Ning hears of a competition to find the kingdom's greatest shennong-shi - masters of the ancient and magical art of tea-making - she travels to the imperial city to compete. The winner will receive a favor from the princess, which may be Ning's only chance to save her sister's life.

Sancia Grado is a thief, and a damn good one. And her latest target, a heavily guarded warehouse on Tevanne’s docks, is nothing her unique abilities can’t handle.
