When Dr. Gul Delani receives a call in the middle of the night from the Sindh police, she thinks they may have finally found her niece, Mahnaz—a precocious, politically conscious teenage girl who went missing three years prior. Gul has been racked with grief since Mahnaz’s disappearance, and distracts herself through work: she’s a talented curator at the Museum of Heritage and History in Karachi, one of the country’s leading experts in archaeology and ancient civilizations, a hard-won position for a woman.

But there is no news of Mahnaz. Instead, Gul is summoned to a narcotics investigation in a remote desert region in western Pakistan. In her wildest dreams, Gul couldn’t have imagined what she’d find there: amid a drug bust gone wrong, there is a mummy—life-size, seemingly authentic, its sarcophagus decorated with symbols from Persepolis, the capital of the Achaemenid Empire. The discovery confounds everyone. It is both too good to be true, and for Gul, too precious to leave in careless or corrupt hands.

Aided by her team of unlikely misfits, Gul will stop at nothing to get to the bottom of it, even as her quest for the truth puts her in the throes of a dangerous conspiracy and threatens to collide with her ongoing search for Mahnaz.
