Here's something cliche that you've definitely heard (read?) in reviews before that I'll plagiarize: I thought I wouldn't like it, but I ended up really liking it instead. I mean, I judge books by their covers sorry and this didn't look too appealing. And, it's a horror story, and I'm not a fan of horror movies. Despite my expectations, the first sentence hooked me in. 
 If I were to give you an example of something called an unreliable narrator, then THIS IS IT. At first, I thought it was ghosts doing the abnormal crazy things. 
 (view spoiler)[Like: her phone says that she texted things twice or thrice. Sometimes others would get random gibberish texts. Sometimes she'd post journal entries twice - at first I thought it was ghosts who did it. (hide spoiler)] 
 Then I realized that it was actually the person doing the action who actually did it, instead of the ghost. The twist in the ending :O :'( And it turns out that technically, there's no ghosts. Or not as people normally think of them. I feel like I'm including too many spoilers? 
 I really liked the format it was in - a journal? Online diary? Most of the time annoy me - maybe because they're not written well - but this worked out pretty fine. 
 Anyways, this wasn't really that creepy (maybe I did freak out a few times), but it was pretty good.
