Did you know that farmers can use bug armies to protect their crops? Polly, a praying mantis, comes from a bug-lab bred to fight on an organic farm. Too scared to fight, she saves a little aphid named Jackson, and becomes a traitor to her mother, the colonel. They make friends with Emack, a rose-eating, spotted bat, and together, the three go on a journey to find The Garden and live peacefully in The Special Apple Tree. Surprised by a crop-dusting airplane, Emack is knocked out and they fall to the conventional farm below. In a strange land covered in bug-poison, they meet a girl named Greta who's battling an illness, have a run-in with mutinous bees, get abducted by mutants, and go on trial for Polly's life. Will her brave solution give everyone peace, and a chance for long, fruitful lives?
