Harriet Potter, a Re-envisioning of Harry Potter

Harriet's nearly thirteen, but she has to act much older. Her Aunt's a neglectful mess and her older cousin's a bully, not to mention she has sweet Verna to look after. When a giant man shows up promising magic, Harriet wonders if this is the way to fix everything. But Hogwarts isn't exactly what it's been cracked up to be and foes don't always look like foes.
