I don't know. It's kinda interesting, although the idea has been used many times.

The blurb gives the impression that something "out of this world" happens to the childhood friend, when it's just a "little" accident. Okay, falling from a "bridge" of a waterfall isn't something that happens everyday, but considering it's about aliens, you'd expect a bit of a different accident.
Anyway, even if it's a bit of a clickbait, it still is what it says. Although not really the typical aliens you'd think. At least not so far.

The story is pretty straight-forward and seems like it was written for kids. Apart from the horror and dark artstyle, that is. Things are explained a lot and mysteries uncover pretty quickly.

My only mistake was to read this while eating dinner. There's lots of body-gore.

I might continue this, but I'm not very eager. It's pretty clear where the story is going. There's no romance tag, but it definitely is part of it.
I'd rather have the plot about the aliens, than what it is now. But I don't have high hopes. Series like these usually lose themselves in unnecessary drama.
