Missing: Oakland Harbour - Cassandra Doon

Just yesterday, she was a 20-year-old working at the diner to make ends meet.
But today, at 21, she finds herself being whisked away to a school of magic to develop her powers.
They claim she has four, but that seems impossible; her alcoholic mother can barely function and her father ran away when she was just an infant.
How could there be any magic in her blood?
And as if that wasn't enough, three of the most attractive men at the school seem to have taken notice of her as well...
