Eloquent Ruby by Russ Olsen

The ruby community is full of un-written rules, conventions that people have agreed upon over time which can be a little confusing for somebody who is trying to learn Ruby for the first time.

Eloquent Ruby provides a good overview of the Ruby language explaining some of the conventions the community has adopted. A good read for beginners and even advanced developers.
