Alex has an imaginary friend. The only problem is he's a demon who convinces her she must murder friends and family to prevent an alien takeover. Is he real? Is he telling the truth? Or is Alex delusional?
A very imaginative and original story concept - gruesome and erotic in a few places, but filled with tension and conflict as the demon exerts more and more pressure on the teenager.
I've read a few other books by Ms Hinsley, and have to say I enjoyed the others more, probably because teenage drama wears me out, but this is still a very good read.
