Scythe

In the future, death is a curable condition. People can live forever. However, this would lead to massive overpopulation. To help control the growth, Scythe's are ordained to take lives. They are above the law and attempt to take people at random. They go through training and apprenticeships and are expected to show caring in their actions. However, as time has progressed, bloodthirsty scythes have entered the ranks. The story tracks two apprentice scythes and their work to uncover the problems in the order. 

This book is an interesting take on the future world. Some scythe's go to great efforts to try to mimic actual causes of death. If we have invincibility, yet also random deaths does that really amount to much? Perhaps it is the temporary immunity to gleaning granted by the scythes that makes the difference. This seems to enable a new group of haves and have-nots. It is not clear how the deaths by scythes are enforced as "final" while others just leave somebody "deadish". Would there be other attempts to work around the system?
