I'm just going to come right out and say it, "I don't understand Imaginary Girls at all". I suppose I get that it's a mystery but at the end of it all, I'm not convinced I understood anything at all. 
 Basically, this is Chloe's story where late one night, she discovered the dead boy of her classmate left floating in the reservoir. She moves away but her older sister, Ruby, will do anything to get her back and when Chloe returns to town two years later, deadly surprises await. 
 I will say that, there were a few good surprises in Imaginary Girls but apart from that, I wasn't very impressed. I was actually worried because Chloe's older sister, Ruby, is apparently, "the girl everyone looks to and longs for". It's scary actually how everyone in town is infatuated with her and will do anything for her and how Ruby can even influence the town with a few words here and there. It sounds like she's a psychopath in the making. 
 Anyway, I don't really know what else to say about Imaginary Girls except that it was very surreal and I wasn't sure what to make of it. Check it out if you want something different on your reading list!
