Bonjour !

Je suis nouvelle à la langue Fviens de me lancer dans l'apprentissage du française et veuxoudrais des recommeandations de livres.

"être nouveau en français" isn't said. I've suggested a natural alternative
se lancer dans = to engage in, to embark on (to make the decision of starting something new and actually start it)

"je veux" isn't very polite, it really sounds like you're ordering your lackeys or employees around
The conditional is used when making a polite request => je voudrais
Adding a "s'il vous plaît" (or "s'il te plait", in the case of one person you're familiar with) never hurts either

Merci !
