Review Detail of Whaa in The Zombie Knight Saga

Have your heard of Worm? This is comparable in quality and quantity. The main character is Hector, a young black man who commits suicide but is brought back by a Reaper in exchange for his services. It starts small then explodes. The superpowers/hard magic system runs on some background fundamentals that are just coming to the forefront, I guess in that sense one could compare it with the Cosmere books. The update speed is quite slow and the author is prone to going on hiatuses, you're forewarned.
