Invisible Isabel

"Isabel Beane is a shy girl who lives in a home full of havoc and hubbub and hullabaloo. With five siblings, there is always too much too much-ness. At school, there's a new girl who is immediately popular, but she's also not very nice to one person--Isabel. Isabel has never felt more invisible. She begins to get bombarded by fears, like being abandoned by her classmates and taking the upcoming Extremely Important standardized test. Her fears feel like worry-moths that flutter in her belly. With every passing day, they seem to get stronger and stronger. How can Invisible Isabel make people listen?"--Amazon.
