The stakes are higher than ever in the third book in Amy Ewing's Lone City trilogy. Revolution is brewing, and for Violet the fight has become even more personal – her sister has been kidnapped by the Duchess of the Lake.

The third book in Amy Ewing's New York Times bestselling Lone City trilogy, The Black Key is perfect for fans of The Selection and Red Queen.

Violet and the Society of the Black Key are preparing to launch an attack on the royalty, and Violet has a crucial role to play. She must lead the surrogates as they infiltrate the Auction and break down the walls of the Lone City. But with her sister, Hazel, imprisoned in the palace of the Lake, Violet is torn. In order to save her sister, she must abandon her cause and her friends and return to the Jewel.

The actual ending (the last few pages) were really quite lovely, and I am glad that there was an ending with such freedom for a character who had seen very little of it. * Books for a Delicate Eternity *
Such a wonderful debut series that is often underestimated by readers. Thoroughly enjoyed it. * Diva Booknerd *
Overall, I really enjoyed this series! There were many mixed reviews about this but I found it highly enjoyable and a light, not too difficult read that’s easy to get into! The added bonus of the beautiful covers and cute romance just makes things better! * The Sprinkled Pages *
