Anna was, without a doubt, completely oblivious to the fact that anyone could sense her. That didn't exist in her world, people couldn't sense her, and she just didn't sense anyone else. It just wasn't part of her power, or anyone else's for that matter. So while she was curled up in the chair, completely zoned out from the rest of the world, she had no idea that someone had been looking at her, for any reason what so ever.
After a minute or two she set the book down on the table, and stretched out in the chair. Good book, but maybe she just needed something else to read, something new. Rolling off smoothly from the chair, she stood up and moved toward the book stacks again. Her eyes fell on a girl she hadn't seen in the library when she first came in. Anna looked in her directions meeting her eyes. She offered a smile, it was what she would normally do when she was feeling herself. She walked a few steps past the girl, and then turned to stop infront of the stack she had been walking by.
Her fingers reached up, lightly tracing over the books as she read through authors and titles. A lot of them she had read, a few she had never heard of, some of them caught her eye, but she was feeling extremely indecisive today about what she wanted to read. Almost restless about it. She pulled down one book, read the back and slipped it back. Not quite what she was looking for.
Turning around, she checked the other side of the stacks.
