Mostly Monty by Johanna Hurwitz
Candlewick Press ISBN 9780763640620
Meet Monty, or more precisely Montgomery Gerald Morris. He has a nickname, a birthday - and asthma. He doesn't have a brother, a sister, a pet or a best friend. Monty spends his time working out how to do things his own way, such as finding a pet, discovering a new hobby and making friends.
