Book 1

Royal Decoy

by Heather Frost

Published 15 June 2020

Clare made a mistake when she saved the princess's life . . .

In one horrible night, Clare is forced to give up her life as a kitchen maid to become the princess's decoy. Thrust into a dangerous new world of royals and deadly politics, she must learn how to be the princess's perfect double to ensure her betrothal to an enemy prince. Desperate to survive, Clare throws herself into self-defense training, taught by her distractingly attractive bodyguard, Bennick. The spark between them is undeniable, though a relationship is forbidden. When a ruthless assassin begins stalking her, it becomes frighteningly clear that some will stop at nothing to end the tenuous peace-and Clare's life.

Across the northern mountains, Prince Grayson is his father's ultimate weapon. His name inspires fear in all who hear it, but no one knows his heavily guarded secret. He carries out every brutal order only because his father holds power over the one person he cares about. Grayson's silent obedience is tested, however, when his father reveals plans to exploit the marriage alliance between two of their greatest enemies. If Grayson submits, the blood of thousands will spill. If he resists, the girl who means everything to him will die.

The fate of Eyrinthia hangs in the balance. Some want peace. Some want war. All will be thrown into chaos.

Royal Spy

by Heather Frost

Published 15 April 2021

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.
