Eliza Bing is (Not) a Big, Fat Quitter

Eliza has had many hobbies in her eleven years... and most of them haven't lasted very long.
After she and her friend Tony create a baking business for a class project, Eliza becomes certain that cake decorating is her destiny. Her parents insist that the summer "Cakes with Caroline" class is too expensive—especially given Eliza's history of quickly losing interest in things.
Desperate to show them that she can be diligent, Eliza volunteers to take her brother's unwanted spot in a taekwondo class. At first, she has absolutely no interest in martial arts, and the focus and discipline of taekwondo is a huge challenge for her since she has ADHD. To make things worse, mean girl Madison shows up in class.
Eliza is tempted to drop out, but a true martial artist never quits. Can she rise to the challenge?
