The Kids in Mrs. Z's Class: Thunder Nelson Does the Impossumble

By Martha Brockenbrough

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 Belpr Honor artist Kat Fajardo, Thunder's story invites readers into Mrs. Z's class where friendship and fun rule the school.
