Why is Liesel drawn to Ilsa Hermann? Be specific.

Liesel felt compassion for Ilsa, found her interesting, and was drawn by the library of books in Ilsa's library.

At times, Liesel wondered if she should simply leave the woman alone, but Ilsa Hermann was too interesting, and the pull of the books was too strong. Once, words had rendered Liesel useless, but now, when she sat on the floor, with the mayor’s wife at her husband’s desk, she felt an innate sense of power.
