It might well do, however Chapters 21 and 22 are very webrat centred, and
you really want to use Capybara instead. Chapter 23 isn't really necessary
if you are using Cucumber and the same could be said for Chapter 24.
Chapter 25 is where you should start using RSpec with rails.

The book is quite old now. It still has great value for understanding core
BDD principles, and for covering the range of things you can do with RSpec,
but if you use it as a guide to follow step by step without sufficient
background understanding you might get bitten by its age. The Cucumber book
might be better to use with Rails for this.

Finally the most important bit of the book is the diagram on page 29.
Understanding that cycle is key to doing BDD well, and the codebreaker
example does have the merit of being a low overhead way of examining this
cycle in great detail, without all the baggage that Rails brings

HTH and Good luck
