Comment:
The book so far is really confusing because there are five stories going on at once.

1. A story of a tower with a light in it. (Best description I ca give of the information. Sorry)
2. A story about an Electric Monk that finds a door in a stone in the middle of a pink (at least the Monk thinks so) valley.
3. A story about Susan who in waiting for a phone call that never comes and she ends up going out somewhere.
4. A story about Richard who goes to a college dinner, it was 10 years after he graduated from that collage.
5. A story about a man named Gordon Way, brother to Susan (lady from story 3.), employer of Richard (person from story 4) and owner and founder of WayForward Technologies.

And that is just so far. In story 4 they also bring up Dirk Gentley. It say that he changed his name a couple of time ad these are the names I know so far. Svlad Cjelli. Dirk Cjelli. He is notorious, sought after and endlessly speculated about.
