Grasshopper Jungle

Sixteen-year-old Austin Szerba interweaves the story of his Polish legacy with the story of how he and his best friend , Robby, brought about the end of humanity and the rise of an army of unstoppable, six-foot tall praying mantises in small-town Iowa.
To make matters worse, Austin's hormones are totally oblivious; they don't care that the world is in utter chaos: Austin is in love with his girlfriend, Shann, but remains confused about his sexual orientation. He's stewing in a self-professed constant state of maximum horniness, directed at both Robby and Shann. Ultimately, it's up to Austin to save the world and propagate the species in this sci-fright journey of survival, sex, and the complex realities of the human condition.
