What is a god?

The author takes us once again into the problem of parallel universes and it is with great interest that we follow the adventures of three main characters: "good" (Leo Bulero, a human-evolved on a boss multiplanétaire firm, Barney Mayerson its Cog (he can see possible futures)) and "the wicked" (Palmer Eldritch who became a quasi-God). They will compete on two drugs (D-liss and K-priss) which allow to translate (move his conscience in individual or collective universe constructed from materials or without).
Anyway as you can see, it takes a little snag but that is worth further aspect anticipation, what are the substantive questions that are asked, such as:
1 / Does everyone builds his own universe?
2 / What is a god?
3 / Is the future predetermined?
and any questions that may arise.
In summary, a captivating and informative reading!
