A DECOY recruited to be a spy.

A PRINCE compelled to become an assassin.

A SERJAH pressured by an unwanted crown.

A WORLD covered in shadows.

Mere months ago, Clare was just a kitchen maid. Now, she is a decoy for Princess Serene and a novice spy, caught in the royal family's web of secrets. While journeying to Mortise to finalize the princess's betrothal to Serjah Desfan, Clare lives for the stolen moments she has with Bennick, the bodyguard who is quickly claiming her heart. But when a notorious assassin is hired to kill her, Clare's life and the alliance hang in the balance.

In Ryden, Grayson prepares to leave for Mortise with his brother, Liam. Their orders are to ignite a war between their enemies, and Grayson has been tasked with assassinating Princess Serene. It may cost his soul, but he is ready to comply, as long as he gets something in return: freedom for Mia, the girl he loves. But the more time he spends with his brother, the more he begins to wonder if Liam is what Grayson wishes he had the courage to be . . . a traitor.

Desfan feels trapped. By his disapproving council, his impending marriage to a stranger, and the imminent arrival of enemy princes who may not want the peace they profess. When a dangerous drug threatens his people, Desfan jumps at the chance to rely on his swords instead of politics. But his investigation uncovers more than he bargained for--a plot that may destroy Mortise from within.

Eyrinthia hovers on the edge of war. Spies. Rebels. Traitors. All must choose a side.
