Moira Whyte refuses to believe the bloody evidence that confirms her brother's death. Instead, she begins to hack into Encephalon, the underground network built to subjugate the entire world. She's right. Her brother isn't dead. He's worse than dead. Trooper A1: The Purple Blitzkrieg is the first novel in the four-book Trooper Series, a raw, high-stakes fusion of biological science fiction and emotional realism. Written by Gabrielle Marie Kozak at just sixteen, this debut launches readers into Kozak's world, where humanity's faith and courage are put to the ultimate test.
