In this book, Ethan and Emily Tuttle using the money from their theater organize a children's entrepreneurship market where kids can show their own businesses. The twins then decide which businesses to loan money t0. The twins have to decided which kids are likely to succeed and invest wisely. The twins not only invest in other kids but meet a new friend, Mattox. My favorite thing about this book is kids helping kids. If you are interested in purchasing this book click on the picture below.
