Caroline L. Perry has always thought that Aussie animals are amazing, but a close encounter with a quokka made her the happiest human on Earth. Born in the UK, Caroline hopped around several countries before settling in Los Angeles, California. When she isn’t working on her children’s books and volunteering as a kids’ writing coach, she spends her time planning adventures with her Kiwi-Aussie husband and their three mini-marsupials, who can always turn her frown upside down. Caroline is the author of The Corgi and the Queen, I Am Not Happy!, I Am Not Grumpy!, and more forthcoming books for young readers. Say “g’day” at CarolineLPerry.com.

Sydney Hanson is the illustrator of Construction Cat by Barbara Odanaka and I Am Not Happy! and I Am Not Grumpy! by Caroline L. Perry. She was raised in Minnesota alongside numerous pets and brothers. When she wasn’t tunneling through snowdrifts or rescuing frogs from rain gutters, she was drawing. Her illustrations and paintings still reflect these early adventures and are marked by a love for animals and the natural world. She lives in Los Angeles where she’s worked for several animation shops. In her spare time, she enjoys traveling and spending time outside with her adopted brother, a Labrador retriever named Cash.
