For two years Nicky has wandered the dark empty corridors of the overgrown Thorn Hall, unseen and untouched, feeling like a ghost. His only company, the cold man who promised to keep him safe from harm, Lance. But when Lance dies, Nicky’s assurance of safety disintegrates and his world suddenly becomes a lot more real and a lot more dangerous. Scared to leave the house, Nicky longs for daylight. He employs a gardener to clear the over-grown bushes and vines that have nearly swallowed Thorn Hall whole. The last thing Nicky expects a little light to do is show him something to fight for. Eighteen months in a young offenders’ institute has taught Cai two things: he occupies the playful puppy end of the How Dangerous Are You? spectrum, and he has an unfortunate knack for being in the wrong place at the wrong time. Desperate for a job, he takes the first offer he gets. Even though Thorn Hall creeps the hell out of him and he barely knows one end of a pair of garden shears from the other. Things start to fall apart when Cai is drawn into Nicky’s strange world of sticky notes and secrets. Cai finds he is now a target, blamed for a crime he didn’t commit. Desperate not to go back to prison, he digs deep and risks all the good things in life to help Nicky run. But now Nicky has someone he wants to protect, he knows he can’t run any more.
