"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.
