In terms of don't mess with drugs messages that have appeared in Red Eye books this is the better one. So this was one of the first Red Eye books that were published and I have owned a physical copy since then. It's one of the better ones, so it shame I left it for so long. I have read all the Red Eye books now but Fir by Sharon Jones (working on it).

The Red Eye books are quite happy to have terrible ending which is one of the reasons I appreciated it. The characters stop sleeping and therefore go insane. There are some background stuff hinted at and I feel like we don't get a straight answer about. It doesn't matter.

The Horror starts after Lizzy and her pals take terrible smelling pills (the first major red flag) and after the horror of exams, the shadowy images start appearing from the group and they turn against each other.

The book is in first person, in Lizzy pov, which works well, especially when they start betaying each other.

Overall, I give it 4/5 stars for .I think I rank it under Frozen Charlotte but higher than the other four stars books in the series ( Flesh & Bones, The Haunting and Charlotte Says). Actually, I don't know. The Red Eye Series started badly for me, but overall the series on avange the series sits at 3.6. Yeah, one star can really tank an avenge when you do the maths. It could be rounded to 4 stars which is what the series actually sits at for me.
