The first book in bestselling author Kenneth Oppel's explosive new trilogy 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.
