Brian Greene - String Theory

[pl1ngpl0ng]

One of my sons are soon going to
Australia to study psychology. 
I want to give him a gift for the courage he display by travel to the other side of the planet to gain knowledge of an academic subject and following his dreams. 

Its not about psychology but i have just started to scratch the surface of string-theory, for me this has been an epiphany... 
I feel like the ancient wisdom of Pythagoras
"The Music of the Spheres" now 2500 years later manifested in the m-theory, is something that i really would love to pass on to all my children. (young adults)

Has anyone here on UM been reading any of these books by Brian Greene? I was wondering about which one to give him and maby pique his interest. So if someone could point out maby the most entertaining book to start with, i would be grateful. Im going to buy and read them all but i dont got the time before my son is leaving.
