SOLVED. Dystopian, vampires(?) /s

[Elise]

I read this in the last few years I think.

It was based around this community of people who lived inside a wall, they patrolled it at night and kept it lit up because there were vampires or something like them that generally travelled in groups of 3 and would try to get in.
The main character was a woman and she worked as a guard on the wall i think.
The children in the community all grow up and are educated in one area and are kept unaware of how the world really is until they turn a certain age and join the rest of them.

Eventually the main character and a few others leave the community, i think to check on a power station they haven't had contact from but should have.

They stop at an abandoned shopping mall on the way and get attacked because the vampire things hide out in there during the day and i think the main character finds a little girl or someone underneath a carousel.

I think they lose one of their group here but they survive and find each other later.

At the power station they find one survivor and rescue him and hole up there, i think it has an electric fence around it and i think theres a room underground.

I can't remember any names or how it ends sorry. Appreciate any help, thanks :)

Erica Stevens, The Captive Series Bundle: Books 1-4. Vampires, humans, and evil ex-vamp creatures that bury themselves in daytime and come out to hunt EVERYTHING at night.

Vamp's rule, humans are either 'blood slaves' in effect or rebels generally.

Nope, not that one.

I'm not sure that they were actually called vampires in the book... they might have been called something else and i've just assumed they were vampires or something like them.

But they weren't organised like it sounds like they are in that book series and there weren't blood slaves. I think they acted more like rabid animals.

Oh i've figured it out!
It was the passage by justin cronin.
it jumps back and forward in time and i had just focused on one part. And they weren't called vampires they were called virals, i knew there was something about that
