help me choose a ruby book

could any1 recomend a book i could buy for my girlfriend shes a computer
programmer and deals in ruby rails i dont have a clue , there are a few
on amazon could sum1 help me pick a decent 1?

Sure she hasn't read enough ruby/rails material already? I'd shoot for
the fiction shelves instead, unless you know she really wants some
specific rails book.
