Dani and Jax by Tricia Cundiff - Fruit of the Spirit Series Book 1

Dani was a good girl. At least she thought so. She was pretty sure her teacher didn't think she was good. Her teacher was unfair, and Dani was being punished. Everything was very unfair and Dani was not happy about it. Who would guess that a little purple goat could change things? Join Dani on her adventure with Jax, the purple goat only she can see. Jax is very smart for an invisible goat and helps Dani laugh her way through the things that seem unfair.
