A string of deaths of young, healthy people, including the athlete son of a US senator and a pop star/influencer, spurs a joint investigation by Canadian detective Anson Chen and his US counterpart Cari Garcia. The victims are dying with the same symptoms - extremely high fever and uncontrollable seizures leading to brain death. The common factor is a toxic substance called DNP which was never intended for human consumption but is now being marketed on the dark web as a weight loss miracle drug. Can the combined talents of Garcia and Chen, along with medical input from toxicologist Dr. Julie Rees, stop the spread of DNP and put an end to the carnage?

I always find Kalla's novels, with a blend of medical insight and detective work, an entertaining read. This one is no different - with quickly moving action, decent dialogue, and a few little plot twists to keep you on your toes. The one criticism I would make is that I think he could do more with the setting and creating a unique sense of place in this series. It is a picture perfect setting on the west coast and I feel he could do more with that. Otherwise this is a reliably entertaining book in this medical/detective series. Thanks to NetGalley and Simon Schuster Canada for the digital copy.
