"Structure and Interpretation of Computer Programs" <- MITs CS text book for years. You will build a complete Scheme implementation by the end of the book.
"Confident Ruby" <- great book that has had a very positive effect on the way I use Ruby
"Practical Object-Oriented Design in Ruby" <- On my reading list, having a huge impact in the ruby community
"Smart and Gets Things Done"  <- great book that has greatly affected how we hire
"The Pragmatic Programmer" <- Classic CS/SE text, heavily influential
"Cold as Ice" (and its series) <- Great hard science fiction novel (I have spare copies)
"Ender's Game" <- I despise the author from the bottom of my soul, but his books are good.
"The Mythical Man Month" <- Classic project management text, heavily influential
"Surely You are Joking Mr. Feynman" <- Richard Feynman's autobiography. Hilarious.
"1984" <- because 2016 will be like 1984.
