Lisa Holiday is Agent Brand's second in command, and is also the school librarian. She usually briefs the team with all of the information they need about where they are going, and how they have to act. She has blonde hair and wears glasses, is really pretty, really nice, has a slim figure (and when she wears her black spy suit, Agent Brand is hooked!), and is a great librarian and spy. She and Agent Brand have estabilshed a strong romantic relationship. Ms. Holiday has a motherly feeling with the N.E.R.D.S. She treats all of them like she would treat her own child, if she had one. She is having a good effect on Agent Brand, who is now slowly warming up to the kids.
In the fourth book, she has the villain virus implanted in her, and she became the villainous Miss Information.
In the fifth book, it is revealed that Ms. Holiday is really a villian by the name of Miss Information and a Russian spy named Viktoriya Deprankova. She builds a time machine and tries to remove the NERDS from existence by messing up past family matters. In the end, Agent Brand goes back in time and fixes her corrupt history, making her a member of the NERDS again.
