This comic is much darker and grounded more in the real world. It's about what happens when people fall through the cracks and how the world can feel like a completely different place at night compared to during the day.
I liked all that about the series and I also liked that it had a story to tell and then wrapped up. It's not a long drawn out series. It's only twelve comics in total and I grabbed them as a set from Comixology.
The only thing I didn't really like were the religious overtones (and undertones for that matter) which ended up tying into the main story. It wasn't too heavy handed or focused on any one real world religion but it still felt like a bit of a cop out in an otherwise unique world.
If you're in a dark and broody mood and want a comic series to match, check out Midnight Nation.
