Book recommendations?

Hello everyone. I've been out of the coding/designing scene for a few years and looking to get back into it. Previously I worked with a lot of PHP, and a friend suggested I check out Ruby. I find I learn a lot better out of a book than a webpage, so I am here to ask if anyone's got a recommendation for any particular book? There are a lot marked five stars on Amazon. I've had __ for Dummies books and a few PHP books, but the authors I liked have not written any Rails books :)

I appreciate any suggestions you can offer and look forward to jumping in!
