It's never really been my thing to be the brave one - that's always been my older brother Patrick - but something world-changing is happening in our small town of Creek's Cause. Parasites have infected everyone over the age of eighteen, making them violent, and if they even sniff a kid they either bash our brains in or take us back to their creepy lair. We're trapped at the school with the other remaining survivors, including Patrick's girlfriend Alex, and we don't know how long we'll last. The school is surrounded by infected adults, and we're sure that there is something else out there, something controlling the people that used to be our parents, our guardians. But here's the real problem, Patrick is turning eighteen in a few days, so it's up to me - Chance Rain - to find a way to save him. And maybe, just maybe if we survive the next few weeks then we can help save humanity.
