Meet the kids in Mrs. Z's wacky and wonderful third grade class! When Mrs. Z's class is looking for an animal to "adopt," Thunder Nelson knows just the critter--the baby possum she just saved. But Thunder isn't ready for what happens when a wild animal goes to school!

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.

Both sweetly poignant and laugh-out-loud funny, with black-and-white illustrations by Pura Belpré Honor artist Kat Fajardo, Thunder's story invites readers into Mrs. Z's class where friendship and fun rule the school.
