The original French fairytale has three daughters. In fact, instead of reading Beauty, you should go read the original (http://www.gutenberg.org/ebooks/7074).* Although if you are interested in going on a Beauty and the Beast retelling kick, let me tell you, I have been there and back (and enjoyed the journey!). Beauty is closest to the original tale, but my favorite reimagining is Juliet Marillier's Heart's Blood, because it is everything that my Beauty and the Beast meets Jane Eyre with werewolves story wants to be and isn't (yet).

*Technically Beaumont's telling is not the original, it's an abridgment/retelling of an earlier story by Villaneuve...but having read them both, I can safely recommend Beaumont's. It's a better read.
