Plagued with darkness, burdened by sadness, hurt by life.
A book so mysterious that there's no description.
Read it and weep.
Figure it out.
Have fun.
But most importantly, enjoy being disappointed.
I'd like to consider each part a story in itself. While I always connected the characters with each other, something felt different in each part. It's a story about many aspects of our thoughts, some of which never have touch with reality, and some we see every day. You might not understand this unless you travel inside the characters thoughts, and yours for that matter.
