Lila's class is on a field trip to the zoo. While busying herself making shadow puppets on the ground, Lila notices a group of students pass by that, strangely enough, don't cast any shadows! When one of the students accidentally drops a strange pendant, Lila hurries after him in order to solve the mystery. This text provides a good introduction to the genre of science fiction.
