Dune

The book i have been reading is "Dune." So far the book follows a boy named Paul Atreides who is the son of a duke on the planet Arrakis. An old woman came to him and first gave him a test to see if he was human or not, i think there is another meaning behind the test but i am not sure at the time. After the test the woman informs him of some things such as the past. The next chapter seems to be the duke discussing politics or economics of the planet to someone else but thats as far as i have read.
