Thunder Nelson Does the ImpossumbleThunder Nelson Does the Impossumble

"Mrs. Z's class is voting on a small class mascot, since big animals tend to get all the attention. But Thunder hates voting--it's like sports but less fun. Everyone is nominating tardigrades, while Thunder is hoping for something fuzzy, like a hamster. Then she finds an abandoned baby possum and has a brilliant idea. She'll bring the possum to school and convince the class it should be their mascot! How could they resist picking a real, live animal? But when Thunder's plan goes off the rails, the possum--and the class--may end up in danger if Thunder can't find a way to fix her mistakes."--
