Really? I thought Avaritia was straightforward. Once I got into the feel of the story, it was pretty simple.
Cass goes through the different timelines destroying them, until he finds out the identity of Newman Xeno, so then he goes killing every Desmond Diamond he can find, but he starts to develop a conscience from destroying all those worlds and then he has a manlove with Diamond. So he creates Newman Xeno.
Gula left me really discombobulated. I have to go read it again.
At first I was really skeptic about the colours as well. I liked the monotone look of the book and thought it really made it stand out. Once I saw the colours I was sold.
