"The Art of Computer Programming" is a great book

Also recommended from Neal Stephenson: The Diamond Age.

maybe you'd like Louis McMaster Bujold's Vorkosigan Saga

I would give God Created The Integers as a reference to read up to where you are in math, not as something to get through.

God Created the Integers: The Mathematical Breakthroughs That Changed History. Stephen Hawking.
