I froze with her?

I had the chance to make myself look good in front of this girl. The only thing I was able to get out was what does she like doing in her free time. We both work together and I am normally quiet. I just normally ask her this book she is reading, or the music she is listening to at the moment. Other times it just things she says in the moment. This time she was quiet and I didn’t know what to say other than that. I want to know everything about her, but just couldn’t think of it. I consider myself a quiet person in general, which I figure she knows from work. I don’t know how to start talking and keeping her interest. I need some help.
