The tiny coastal town of Banyan looks like a postcard. Quiet. Beautiful. Peaceful. Just the place for a working holiday away from city noise, traffic, pollution and crime. So Tom and the rest of the Teen Power gang think. But, in this little backwater, nothing is what it seems. Frightening things are stirring beneath its calm surface. And very soon, Tom and his friends are out of their depth, and struggling against a ruthless, unknown enemy. An enemy who will stop at nothing to keep them from learning the secret of Banyan Bay.
