10 weeks old is fairly young. At that age they really haven't had much socialization. Just be patient, as a month is not much time really. Try to engage her in play with toys. Talk to her, even when she's hiding. She'll hear you.

If she was feral before you got her, chances are her mom taught her to be fearful of humans, and even at that young age they learn that lesson well. Just be gentle and talk soothingly to her. As much talkig and handling as possible, and the more you can devote to her the better. My Abby was a major hiss-scardy cat. Today she is 6 months old and one of those cats who welcome people at the door... believe me, this meeting people at the door thing is new within the past few weeks! Its taken me 5 months to get her to be social! It could take another cat less time (her brother was social from day one) or it could take more time. Just be patient and work with her. Its ok to pull her out of hiding to give her loves and treats. She'll soon associate being taken out of hiding with good things.
