A Good Summer Read?

binaryhead asks: "Well, the semester has just ended, and I have graduated from school! :-) I start my full-time job in a month and want to read a good book in the mean time. Having read Snowcrash, Neuromancer, and most of the hacker biographies, I am trying to find a scifi-geek-hacker book that people like. I might try the new Kevin Mitnick book, but I wanted to see what Slashdot preferred. Thanks."
