Alien in the Classroom (Nancy Drew Notebooks #23)

Description

According to the National Snooper, the queen of planet Zagon is on Earth. It seems pretty silly until Nancy and her friends have a new substitute teacher, Ms. Zagon. Kate Zaleski says Ms. Zagon is an alien. Nancy says she’s not, and she’s going to prove it—along with the aid of a talking parrot who’s helping her solve the whole mystery.
