Severance

If you're looking for a literary dystopian or commentary on the worker-drone routine then look no further! But if you're looking for an adventurous, zombie end of the world story, look elsewhere. 

The book is told in different timelines, and I enjoyed the past/lead up to the End way more than the present day plot line. 

The author did a really fantastic job showing how being stuck in routines, going on auto-pilot is a modern epidemic. Enter our main character, Candence. Even with the world ending and everyone turning fevered, she faithfully continues to go into the office until her contract expires. Very ironic considering the Shen fever turns people into zombies stuck on an infinite loop of routine.
