How do you say...?

Hi,

How do say "These are Anna's books, could you return them to her for me?"

Thank you so much ^^

これらの本はアンナのです。彼女に返してくれるかな

sorry my katakana for anna is probably wrong but the sentence should get you taken care of I think

I think other ways to express the same idea could be:

KORE WA ANA NO HON DESU. (KANOJO NI)KAESHITE KUREMASENKA?
KONO HON WA ANA NO DESU. KANOJO NI KAESHITE KUDASAI.

「（かのじょに）かえしてもらえませんか？」is slightly less direct.
