Is dengue the next pandemic? Two veterinary medical detectives, decades apart in age and experience, battle the tropical disease first in New York City and New Mexico, then in Hawai‘i. Even in paradise, people can’t escape blood-thirsty mosquitoes spurred on by a warming climate. Join these resilient women as they push through personal challenges to discover the scientific truth and stop the relentless death toll.

Faye Simpson abandons New York and a domineering boss to solve the mystery of an explosion in Hawaiian dengue infections. She postpones her blossoming relationship with a younger trans female physician and reconnects with a veterinary school classmate who’s a dengue expert. Maya Maguire, brokenhearted from family tragedies, is thrilled to push aside painful memories in the Land of Enchantment and contribute her disease detective skills.

Despite their efforts, the disease swarms two Hawaiian islands through insatiable mosquito carriers. Lessons learned from initial investigations on the mainland don’t control the threat. Faye has seen nature’s deadly creativity before, and the evil people can do.

Maya’s brilliant analytical work leaves both vets wondering whom they can trust, and what caused the fatal outbreak, people or nature. Can Faye and Maya decipher the mystery of a spiraling catastrophe in Hawai‘i and beyond?
