The Secret Shadow

When another shape-shifter breaks into the castle and threatens the royal family, the search for the intruder begins-and Jezebel fears they'll catch her instead.

The castle is locked down until the danger is eliminated. Everyone is suspect. Still learning the ropes of the secretive Jinni court, the life she's worked so hard for is in jeopardy.
With the Jinni Guard on the hunt for this formidable shifter, it's only a matter of time. Once they discover Jezebel's shape-shifting Gift, her future with Prince Shem-and all her carefully formed plans-are over.
Jezebel must persuade the prince to buy her time, so she can track down this unknown shape-shifter before the Guard. If she fails, she'll have no choice but to flee before the Guard discovers her hidden abilities and severs them immediately-a fate worse than death.
The Secret Shadow is the second book in The Queen's Rise series, inspired by your favorite villains in Snow White, Sleeping Beauty, and Beauty and the Beast. Over a century before Queen Jezebel crosses paths with Arie, Rena, and Nesrin, she's just an innocent Jinni girl... who was betrayed.
