Agent Fatma is called to investigate the deaths of all members of a secret society, and assigned a new young partner, the latest woman in an organization that is overwhelmingly male. So a bit of old-cop, new-cop, plays out throughout the story, where Fatma learns to trust her partner.

There’s plenty of sluething and subterfuge at play in this book, with a fantasy, sci-fi, and whodunit mashup. Clark keeps the pages turning, with occasional head-scratchers. For instance, why does Fatma routinely make mistakes in how she conducts her work with Djinn, when that’s her job?

However, the general grist of the story is strong, the characters are engaging, and the surprises are truly surprising. I recommend it.
