books

i've got holidays for the next couple months and i've got no social life or off-line friends to speak of.
what are some good text books i can read during this time?
any subject is fine really, as long as it's somehow related to computers.
and by 'good' i mean detailed and thorough, not fun to read.

Update here. My Intel books finally arrived this morning. They are in paperback, and smaller then A4 size. They are about the same length as SICP (pictured), and around 1cm wider
