I'm actually not sure. I think the brotherly relationship between Header and Thorn is what originally had me hooked.

Most Zombie and Vampire tales focus too much on the monsters and not enough on the protagonists (don't get me started on the monster protagonist stories).

With all due apologies to @TheAverageFan , the monsters in this were almost an add-on. The building of relationships between some of the characters, most notably the soldiers and Thomas and Brooke, made me curious as to how they would (or would not) survive. The other relationship I was hoping to see more of was Reed and his father. But that would been real tough to include.

Silvan was also interesting as the all round evil archetype. The monsters were okay as expendable bad guys but Silvan and his past with the soldiers was interesting.

Remember a story is only as good as it's main characters which inevitably leads to their relationships. So what seems like action, is generally just filler.

At least that's how I view it.

The more I digest this story the more I liked it.
