Royal Gambit

When the heir to the throne dies suddenly, his sister is forced to step up. Princess Louise is unprepared for the job, and there's so much she doesn't know. Like the fact that her childhood friend, Alix, is actually a bodyguard positioned in her life by the mysterious Checquy to protect against supernatural threats to the crown. Or the fact that Alix suspects foul play in the Prince of Wales' death.
With Louise's elevation in rank, Alix goes from operating largely in shadows to standing directly in the spotlight. Her skills are tested to the limit as she tries to hide her powers and the world of the supernatural, while investigating a royal assassination, protecting her friend now she's in the firing line, and all while appearing to be the perfect royal companion. Not even the Checquy could have trained her for this.
The long-awaited fourth instalment in the acclaimed Checquy Files, Royal Gambit is O'Malley at his brilliant best. Perfect for fans of The Umbrella Academy and The Dresden Files.'It is extremely difficult to explain just how thrilling, entertaining, witty, and jawdroppingly original the Checquy novels are. O'Malley's world-building is astonishing.
