King’s Cage Age Rating

King’s Cage age rating is 13 and up. However, I will suggest rating 15+ as there was much more mature content in this book than in the others, This is a great read for adults and older teens who want a great dystopian novel.  In addition to the content, the political complexities of the story may be less interesting to younger teens.

King’s Cage Official Storyline

In this breathless third installment to Victoria Aveyard’s bestselling Red Queen series, allegiances are tested on every side. And when the Lightning Girl’s spark is gone, who will light the way for the rebellion?

Mare Barrow is a prisoner, powerless without her lightning, tormented by her lethal mistakes. She lives at the mercy of a boy she once loved, a boy made of lies and betrayal. Now a king, Maven Calore continues weaving his dead mother’s web in an attempt to maintain control over his country—and his prisoner.

As Mare bears the weight of Silent Stone in the palace, her once-ragtag band of newbloods and Reds continue organizing, training and expanding. They prepare for war, no longer able to linger in the shadows. And Cal, the exiled prince with his own claim on Mare’s heart, will stop at nothing to bring her back.

When blood turns on blood, and ability on ability, there may be no one left to put out the fire—leaving Norta as Mare knows it to burn all the way down. (Publishers)
