Planet 51: Lem Saves the Day (I Can Read Book 2)

Everything seemed to be going just right for Lem - until the day an alien appeared in his backyard! But Chuck isn′t the kind of alien Lem expected. In fact, as Lem tries to return Chuck to his ship, he learns that this "foreigner" isn′t so different after all. With his entire planet in a tizzy over aliens and zombies, it′s up to Lem to convince his friends that it′s not Chuck that has them panicked - it′s simply the fear of the unknown.
