|“||You—she taped my hands to the desk for misbehaving. She called my mother a witch. She blamed me for everything I didn't do and— No. She has to be dead. Who are you?||”|
Mrs. Leer was Hazel Levesque's third grade teacher at St. Agnes Academy for Colored Children and Indians.
While visiting a small island in the great Salt Lake, searching for Celestial Bronze and lime, Hazel and Leo Valdez run into the goddess Nemesis. While Leo sees her as his Aunt Rosa, Hazel sees her as her old teacher, Mrs. Leer. She remembers how Mrs. Leer would punish her for everything, including things she didn't do. When Nemesis asks her if she ever wished for terrible things to happen to her teacher, Hazel replies that while she did talk about it, she wouldn't want them to actually happen, something Nemesis scoffs at.
- Mrs. Leer is the person Hazel most wants revenge on, as she is the person that Hazel sees when she looks at Nemesis.
