Timekeeper

3.5 stars rounded off to 4.

The concept was amazing but the execution fell flat a little bit. Nevertheless, I enjoyed this story a lot.

The idea of time moving because of clock towers and clock spirits was novel. The idea of mechanics who can feel the fibers of time and fix clock malfunctions was equally amazing.
The bad guy was boring / easy to guess, but the conclusion was nicely done. I feel like the sequels might tell a better story if the world building is explored more.
