Post Apocalypse type setting based on Earth.

Main character gains the ability to raise/control the dead (necromancy) and eventual starts to help other survivors using his 'zombies'

Other humans also receive abilities/classes.

Think it was a relatively new book

found it.. was a little older than I thought
