Jinx It

The world was a dangerous place. Just ask sixteen year old Tabitha Cast, a muggle-born set on to prove that she and others like her aren't lesser. She's smart, brave, and has four Marauders ready to prank first and ask questions later. So it may take her a while to prove her point, but with the help of her friends she's willing to bet five Galleons that they'd win the war someday.
