Tales of Mundane Magic

Nothing too strange ever happens to Gertie and Bridget Mallon.
The sisters don't have magical adventures fighting off dark lords or saving the world. Gertie spends her time learning the skill of enchantment, and Bridget has the ability to see things no one else can see with her left eye, which was bewitched in an accident many years ago.
Sure, they attend Flories Boarding School, where Gertie takes a potions class and Bridget plays basketball, and the occasional magical anomaly takes place, but who doesn't deal with the occasional poltergeist or curse?
Life is relatively calm for the Mallon sisters, but things might not be quite as mundane as they appear.
