This thrilling middle grade novel is a tale of wilderness survival and alien invasion. Oppel writes fast-paced books that are full of adventure and page turning excitement. When an invasive species of carnivorous plant invades the Earth it starts to emit a toxic pollen into the air. Three characters Ananya, Petra, and Seth, who oddly have strange allergies, but not to the alien plant, find they may be the only people that can fight back. This is the first book in a trilogy for readers who are hungry for horror.
