Looking for Trouble is about the older sister, Emma, being asked to watch her younger sister, Abby, by their mother who was trying to get some housework done. Emma's reward for watching her younger sister is a trip to the library and stopping for some ice cream afterwards.
Emma knows that watching her sister may not be an easy job since Abby tends to get into lots of trouble. In fact, Grandpa's nickname for Abby is Trouble. Emma realizes that Grandpa is right about Abby's nickname after having to deal with several problems Trouble has caused in one short morning.
During their nightly bedtime story, Mama tells Emma and Abby about their grandpa and his brother. Great-uncle Tom had to watch over Grandpa just like Emma had to do today with Abby. Emma discovers that other family members had very similar problems with their siblings getting into BIG trouble and decides that this seems to be a common issue within their large family.
