Mastermind by Andrew Mayne


A mysterious electrical storm plunges Manhattan into darkness. As a strange, smothering fog rolls in, all communication crashes. In the blink of an eye, the island seems to vanish into a void.

FBI special agent Jessica Blackwood and brilliant scientist Dr. Theo Cray know this isn’t a freak accident. It’s a sinister sleight of hand. Their greatest adversary, a serial killer and cultist known as the Warlock, has escaped during a prison transfer in New York. A depraved master of manipulation, he promised the end of days. He’s making good on it.

One by one, cities across the globe are erupting in chaos as they disappear into the same black holes. Even for two ingenious trackers like Jessica and Theo, there’s still so much to learn about the pattern to the Warlock’s madness. The voids are just a warm-up for something bigger. To discover it—to stop it—Jessica and Theo must descend into the darkest of shadows—and minds.

Mastermind by Andrew Mayne


Mastermind brings together two of Andrew Mayne’s popular characters in one novel. An electrical storm in New York City starts a mystery that needs the expertise of Jessica Blackwood and Theo Cray. The storm appears to be the work of the Warlock, a serial killer. Jessica is a FBI agent with a history with the Warlock. Theo is a biologist who specializes in forensic science, and has a great track record for catching serial killers.

Mastermind is told with the alternating points of view of Jessica and Theo. Both characters are intelligent and unique. There is a quite a bit science/technology discussion in this book. The story is wild, and it makes for an entertaining read.

This is the first book that brings Jessica and Theo together. I have read The Naturalist series that features Theo, and have enjoyed all of them. I have not yet read the Jessica Blackwood series. I recommend reading Mayne’s other books, but it’s not necessary to have read any of them before reading Mastermind.

Fast-paced and exciting thriller. A good book for fans of Andrew Mayne’s other books.

I received a digital copy of this book from the publisher via NetGalley in exchange for an honest review.
