"It was just rain. But after the downpour, odd black plants begin to shoot up. Suddenly— They. Are. Everywhere. They take over fields and twine around houses. They bloom and throw off toxic pollen—and feed. Strangely, three Salt Spring Island teens seem immune. Anaya, Petra and Seth. What’s their connection? What’s their secret? A week ago, they wouldn’t have thought they had one. But they’d better figure it out fast—the invasion has already begun." --Provided by publisher.
