The Exoskeleton Chronicles

Jeremy Boon is a 35-year-old autistic pest control expert. His father, Andrew Boon, disappeared ten years ago after being part of a military experiment, developing mutant insects to be used as drones. When Jeremy is assigned to fumigate a few floors in a large hotel where foreign dignitaries will be staying, 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 that his father had a hand in creating.
