I devoured this book (a set of three novellas) in three days and really enjoyed it. Brandon Sanderson is such a creative author, and here's yet another book of his that doesn't fail to impress. It tells the story of Stephen Leeds, who creates hallucinatory "aspects" with certain specialties to help him compartmentalize his knowledge to learn things and master abilities. He uses their help to solve mysteries as a way to give himself a purpose. Stephen's cases were intriguing to follow, and his aspects were really fun characters to get to know and get invested in. Stephen himself felt rather flat at the beginning, but as I read further, I realized that was an intentional decision. Because of his aspects, his personality is contained in all of them, so without them, he's sort of empty. It was awesome to watch him grow in this.
The only reason I gave the book 4 stars instead of 5 is because, as a set of novellas, the first two don't relate very much to the third, or to each other. I wish he had found a way to tie the cases into the finale more than he did. Otherwise, a great read, especially for a quiet weekend at home. I would definitely recommend!
