The Answers Lie in the Past. One-thousand years ago . . . Flowing between the mountains of the mysterious kingdom, The Western Hill, flows a just as mysterious river. It has been said that the great Silver Lake is where the Silverbloods got their immortality and invincibility. And though that was regarded as only a myth, everyone in the Western Hill has been forbidden to go any where near the Silver Lake. Including the heir to the throne, Silver Prince Brock. There are only two things in the world that Brock loves—the stars and his little sister, Silver Princess Azaria. Brock has every reason to hate his parents, who have never been anything but cruel to him—little Azaria was the one person in the palace to have ever shown him love. But Brock also has every reason to believe that there’s more to his kingdom’s history than it seems. An eerie mystery looms over the castle, woven in each strand of the tapestries that line the palace wall. In an attempt to stand up against his father, Brock devotes himself to solving the mystery of his kingdom’s history. All while trying to avoid his upcoming marriage to the girl he’s been betrothed to—Silver Duchess Adelaide. A thousand and eleven years later . . . Charleston is falling apart under the hand of the imposter advisor, William Fetlock. With the king dead, Queen Elizah is freed of her tower prison, and has taken back her throne with William as her new king. The people of Charleston are even more divided than before under the new rule of a tyrant king and queen who seek to wipe out all those who refuse to pledge loyalty to them. With Prince Stirling, the only heir to the throne, dead, there’s no hope for the kingdom. Unless Piper, the former Queen’s Assassin can figure out a plan to save Charleston. With the help of the Yohamos—previously advisor to the queen—the assassin was able to survive the incident in the tower, although all of Charleston believes both of them to be dead. Together, they set out to find Terrence, a quirky scientist who might be able to help them discover a way to save the kingdom. Along the way, Piper struggles to find her new identity and purpose now that she’s no longer the Queen’s Assassin. As well as battling something she’s never dealt with before until death of Stirling—grief. Meanwhile, the immortal Brock Masser has been awoken from his Poppyblade induced sleep, and is being trapped in the dungeons of the palace. And there’s only one way for him to get his freedom back. Pledge himself to William Fetlock as the King’s Assassin.
