her
Usage Note
Son is the masculine-singular possessive that agrees with the thing owned rather than the owner, so son livre can mean his book or her book. It also steps in before a feminine word starting with a vowel, as in son amie, and the identical le son is a separate noun meaning sound or bran.
Examples
"Il cherche son chien."
Natural Translation
He's looking for his dog.
