Finished Scythe by Neal Shusterman.
This is set in the future, when death and disease have been conquered. Unfortunately, population control is still an issue so there are people called Scythes who “glean” people and kill them. Some are compassionate and some are bloodthirsty. Citra and Rowan are Scythe apprentices (though they don’t want to be) and their success means immunity for their families.
This book is amazing (no surprise; Neal Shusterman is always excellent). It’s the start of a series and I can’t even imagine what’s ahead.
There’s a lot of cleverness in here. Scythes take on new names based on historic figures of the past, and you can learn a lot based on that (there is, for example, a Scythe Mandela and a Scythe Curie; there is also Scythe Rand).
I absolutely loved this novel and can’t wait to see where the story goes.
