I tried twice. Couldn't get through it, not even to the first murder. Sooooo boring and tedious with vague "clues" that could mean anything, including nothing. Whiney protagonist that doesn't talk to the others much, so it's just her thoughts.
Laughably predictable storyline. Partly because I've already read this story in another book. (I'm not naming the other book because it would be a spoiler for the other if you've read only one, though if you've seen any other review you'll already know which book I'm referring to.)
The book provides no reason to like or trust Josh, yet Mira suspects everyone else before considering him. And then only for half a sentence, after which she goes back to baselessly trusting him. It's not even upsetting when the truth is revealed, because even Mira thinks Josh is an annoying dude with a superiority complex.
