book titles spec or book_titles_spec.rb

Here is the spec and questions.
require 'book'
describe Book do

@book = Book.new
end
describe 'title' do
it 'should capitalize the first letter' do
@book.title = "inferno"
@book.title.should == "Inferno"
end
it 'should capitalize every word' do
@book.title = "stuart little"
@book.title.should == "Stuart Little"
end
describe 'should capitalize every word except...' do
describe 'articles' do

end
specify 'the first word' do
@book.title = "the man in the iron mask"
@book.title.should == "The Man in the Iron Mask"
end
end
end
end



My code to the spec above. Any one have any better ideas on how to refine it.
class Book. book.rb
def title=(arg)
@title = arg
end
def title
@title.capitalize!
lowercase_words = ["a", "an", "the", "and", "in", "of"]
return @title.split.map { |word|
if (lowercase_words.include?(word) )
word
else
word.capitalize
end
}.join(" ")
end
end
end
