Sibling Rivalry

Isabel and Melanie are identical twin sisters, but they're nothing alike. They're both starting Year 8 this year. What could possibly go wrong?
The problem is, Isabel wants to prove her independence, and that she is the better sister, but Melanie wants to do the same thing. So they start to try to take each other down. But when one little prank lands both of them in hospital, they have to learn the hard way that nobody's perfect.
