Book excerpt: "How does a child become an entrepreneur? While most people prefer the relative safety of working at a job for somebody else, others are more interested in the independence, excitement, and creative problem solving that are all part of starting our own business and being an entrepreneur. But as Ethan and Emily Tuttle learn in their latest adventure, being an entrepreneur isn't easy -- especially when you're up against some tough competition. Join the twins as they dive into the ins and outs of becoming business owners, solving the many problems that pop up along the way."--Page 4 of cover
