FACT: It is estimated that one million people die each year from mosquito-borne pathogens, including malaria, the West Nile virus, yellow fever, and the Zika virus. Fortunately, scientists can now genetically modify mosquitoes to help reduce the transmission of these deadly diseases.

FICTION: But what happens when rogue scientists genetically modify mosquitoes to kill people rather than save them?

In A Lethal Swarm, M. H. Sargent presents another gripping thriller that dives into the covert operations of FROG—a secret intelligence agency dedicated to preventing catastrophic threats before they materialize, regardless of the cost.

When FROG uncovers whispers of a horrifying scheme to unleash millions of bioengineered mosquitoes carrying a deadly pathogen, their elite team of spies is thrown into a globe-spanning chase as they follow a trail of murder and arson in the picturesque Swiss Alps to blackmail and kidnapping in the bustling city-state of Singapore.

However, they soon discover that they aren’t the only ones wanting to secure the deadly mosquitoes—a terrorist group is already one step ahead, leaving them no room for error. Because this isn’t just another threat—it’s a meticulously crafted plan to unleash a modern-day global plague that will kill millions.

And time is running out.
