The price of freedom is always paid in blood.
The sovereigns of the Silver have awakened, but the Queen is a fractured shell of the woman Cam remembers. He hopes to put her back together by finding her son, the missing prince. At least, that's what he tells his friends when he leaves for the Red.
Back in the Blue, Julia's old tormentor Rufus is hounding her at every turn. She's sick of feeling powerless, but she has a plan that will bring the Nobles to their knees.
All she needs is blood.
The Blood Prince is the final book in Josie Jaffrey's Sovereign trilogy, set in a dystopian Europe where vampiric Nobles control the last remnants of the human race.
