Imogen Brine is undeniably strange. Some would even say dangerous. She can make poisonous flowers grow from her fingertips and the "gift? is becoming harder to control. So when she is taken to a secret island off the coast of Scotland to be with other girls like her, it feels like the chance to finally be herself. But something feels wrong, and it isn't just the friction with other girls or the growing tension between her and the son of the island's head of security, Jack.
