Zachary Nixon Johnson, the last private eye on Earth, is back in action in the second book in the Nuclear Bombshell series, and this time the mystery is four times more dangerous. The wise-cracking PI and his AI super computer sidekick, HARV, are hired by Ona Thompson, one of four genetically-engineered super women known collectively as the Thompson Quads. Her sister has been murdered, and she needs Zach to locate the killer. The list of suspects is long—including a butler, security experts, a giant monkey—and the list of motives is even longer. Vengeance, envy, wealth, and fun could all be at play. And in true Zach Johnson fashion, it isn't long before his fedora’s filled to the brim with danger and destruction. But the biggest question facing Zach is what happens if the real killer turns out to be his client . . .
