This story felt very nostalgic, with it being set in an British secondary school and Gilly's primary concern was (before the mural) the play. The story was mostly OK. This book is part of a series where different authors are given the same concept and are told to write a novella. The concept itself is quite strange and obscure. I think if the book had been longer, with more character development, this would've turned out a lot better. There was a nice ending, but it did feel a bit rushed (with Gilly's family being OK with everything, even after Richard explained the unexplainable). Not sure who I'd recommend this to. I'd read it again if I was bored on a long car trip, but it's hitting the back of my shelf for now.
