an interesting read, but I must say the pacing is really really fast. At this rate the entire world will end from an apocalypse before we even figure out who half the people we are suddenly grouping with even are. Alot of people throwing their "lot" in with us and half of them we havnt even known long enough to be on first name basis with, never mind trusting them.
Its going to make for some very shallow relationships at the very least.
The plot itself is very interesting, but it too is going to burn itself out at the break neck speed its building. Too much, Too fast, with no time to allow any mulling, consideration, or even any really tension to build. Drama is only meaningful when the reader has had time to become invested in the characters that are involved.
I'd honestly consider a rewrite before you get to much further in and it becomes impossible. Take time to allow the reader to get to know who is who, what they are about, why we should care (or not care.) Let the characters breathe and bring life to the story, and let the plot line build, instead of just constantly exploding.
Im picking up alot of Supernatural, and Jim Butcher vibes going on. Follow those examples and let things build from one episode/book to the next.
