Where is the instance variable @user set? If it were my code, I'd do
something like this:

def logout
@title = "Login - Books"

name = User.find(session[:user_id])
session[:user_id] != nil
flash[:notice] = "You have sucessfully been logged out #{name}!"
redirect_to :controller => :books, :action => :index
end
