It all starts when seventh grader Lindy Sachs is granted $100 and access to her father's online trading account as a way to alleviate her boredom while she's home sick from school.

Lindy learns something immediately--she is very, very good at e-trading. Her $100 becomes $200. Then $400. And more. With trading talent and access to her parents' savings, the opportunity to make some real dough is too tempting to pass up. In fact, given how well Lindy's stocks are doing, it would be a disservice to not invest it all... Right?
