The premise was really intriguing, I have a fear of spiders which made me pick this book up. But not only that I love me some middle grade books too. 
 With all that said I'm stupefied on how it turns out. It gave me vibe of the classic children's book plot it felt like it has been recycled. I'm really really sorry Miss Oliver I love the Delirium Series and Before I Fall and I know they're from a different age target-audience but I think I won't read much of your middle grade books. Who knows maybe I still would but right now. It is a "No" from me.
