By: Barbara Park 

Park, B., & Brunkus, D. (1992). Junie B. Jones and the stupid smelly bus. New York: Random House.

Summary: Junie B. Jones is starting kindergarten and she does not like the school bus. Junie thinks the bus smells bad and she refuses to get on it. She roams around the school instead and eventualy hides in a closet until she is picked up. 
This is the first book of a series of Junie B. Jones books.  We follow Junie as she grows up and goes through school.
I loved these books when I was learning to read and started reading chapter books.  I think they are great transition book into reading chapter books.  Also, the writing is humorous  engaging, and easy to follow. This book is best for ages 6-8.
