The Complete Exoskeleton Chronicles (Unabridged‪)‬

The entire bug-squashing trilogy in one volume!

Jeremy Boon is an autistic pest control expert. His father, Dr. Andrew Boon, disappeared 10 years ago after being part of a top-secret military think tank that was developing mutant insects to be used as drones. When Jeremy gets the biggest fumigation job of his career, he must use his expertise to protect Elaine, the girl that he's loved since he was a child, and her son Keith, from the gun-toting mutant insects his own father had a hand in creating. 

Because the mutant insects were just the beginning!
