Most of the books suggested here are rather heavy for a holiday read. I suggest The Code Book by Simon Singh. A very readable introduction to Cryptography. Another one that I'd recommend is the Go Programming Language, a concise but excellent tutorial on Go. This is best used by writing programs alongside reading the book, but you can just read the excellent examples and still get a lot out of it.
