These are minor characters in the Lanie Holland books.
Lanie's sixteen-year-old sister, who is a cellist. Angela and her friends (who play the violin and viola respectively) aspire to play for the Boston Pops. Lanie gets quite annoyed because the only song that Angela is playing right now is the William Tell Overture.
Lanie's seven-year-old sister. Emily is in the first grade. She is very stubborn and currently will only eat things that resemble pizza (other than desserts) so her father has tricked her by making other foods look like pizzas. Emily has entomophobia (fear of bugs and other insects) since finding a spider in the sink while brushing her teeth and will not go play outside because of the fear. She does seem to have "outdoor genes" like Lanie and Aunt Hannah. Emily becomes interested in birds and butterflies, a result of getting over her entomophobia.
Lanie's father. Mr. Holland teaches philosophy at a college (or as Lanie puts it, he gets paid to think). He dislikes mowing the lawn, loves to cook, and loves to bat a paddle ball. He enjoys cooking challenges, such as "tricking" Emily into eating things that look like but aren't pizza.
