Infection (The Hive) by Ethan Stand

Penelope Heath is in her final year of schooling. While on an excursion to Sydney a genetically modified infection is accidentally released. Those who are infected lose their individuality and work only for the good of their new species. The infected aggressively attack the uninfected. Penelope and her best friend Tiffany need to make their way from the infected over-run centre of Sydney to Penelope's family property in Queensland's outback. NOTE: This is only 22,000 words. That's about 100 kindle pages. The next episode will be about the same size.
