Jack is in hospital - there’s something wrong with his leg. But when he catches a glimpse of his X-ray, Jack doesn’t expect to see a huge, squirming thing writhing around inside. It turns out two of his best mates have the same problem. And the doctors won’t tell them anything. Then the burning and hissing starts. Previously unpublished, this book is exciting and fast-paced, keeping within the style of the Shades 2.0 series. It is perfect for reluctant teens who still want an exciting, unpatronising read that is relevant to their interests and concerns, but who don’t want to read a longer novel. With a length of only 6,000 words, and filled with drama, this story will appeal to all reluctant teen readers.
