Arcanum Unbounded: The Cosmere Collection

A collection of excellent short stories, this book contains works set on all of Sanderson's Cosmere, his collection of fantasy worlds. Some stories are directly related to other books, though if there are spoilers, there are very clear warnings about which books they relate to. Others are independent, or are set on a completely new world, introducing us to new characters and magic. In addition to the stories, there are descriptions of each world and their respective solar systems, which gives us an entirely new understanding of the fundamental workings of the Cosmere! I cannot express in words how excited reading these descriptions makes me. I recommend reading some of his other works before Arcanum Unbounded, but it contains fantastic short stories and is an essential part of any Sanderson collection.
