Cover art by Ben Baldwin shows a creature crouching in a low tunnel entrance lined with grey stones and partly hidden by green undergrowth and white flowers. The creature has pale skin covered in sparse black hair and it looks a bit like an ape, a bit like a bear, and completely unlike either of those. Book extract reads: We had to keep track of the thing. I grabbed the closest branch on the nearest apple tree. The ancient tree’s distress was like a kick in the balls. As soon as I could catch my breath, I apologised. I’m so sorry. I didn’t mean that. I got the distinct impression I was only making things worse. I let go of the wounded tree. Thankfully I couldn’t feel its pain any more. I walked backwards towards the cottage, watching the hedge for any hint of movement. As I got closer, I heard the door open. ‘Can you see it anywhere?’ I asked Fin. ‘No, I think it’s gone.’ I could tell from her voice I was close enough to get inside before the monster could reach me, even if it crashed through the hedge at top speed. Even so, the back of my neck was prickling as I hurried through the door.
