Let Me In getting more intense than I expected...

I’m still reading Let Me In and right now it’s getting pretty crazy. Besides the fact that about three main characters got killed off. People are getting turned into vampires, and you find out one of the main characters isn’t even a girl (even though she looks like one).
I’ve seen both movie versions of the book but they barley addressed the issue of what exactly the little girl Oskar is friends with is. In the movies they just say she’s a vampire to make it easier but in the book she makes it very clear she ISN’T one, and that she really isn’t anything. Sine her name is Eli (she pronounces it Ellie) and dresses like a girl I assumed she was a girl but I started to wonder why the author never used her or she he just used her name. Turned out her name is Elias and doesn’t have gender. So that was a little surprising (and a little gross because she’s “going steady” with the main character Oskar).
Another small thing I realized about this book is that since it’s translated from Swedish they don’t have some words we do so I was reading a sentence and what would be English for goosebumps translated to goosepimples. Though sometimes little things like that make it hard to understand exactly what theyre talking about especially when they make up words, or they leave things in Swedish.
As the book goes on it’s getting creepier and more uncomfortable to read. Though Eli's caretaker is probably the scariest character. Like it's not enough that he's commiting murder he's also a pedophile and often fantasizes about the children he's going to murder (and Eli). And that is often described with incredibly gross detail that it makes you queezy. The way he murder's his victims is also scary because he hangs them up by their feet from hooks to drain them like a butcher would do with a pig. And when he's finally caught trying to kill someone in a pool locker room he pours a cup of acid on his face, horribly disfiguring him. The way the author describes it actually made me nauseous. He explains how his mouth sealed together and how his face melted off, more graphically than I was expecting.
