The Last Siren

A curse can only be thwarted for so long.
Living on the windy isles she is just a normal young girl, flourishing into womanhood.
Facing boy troubles, and struggling with balancing chores and her social life like any other normal girl. That is until a stranger appears in her kitchen and tells her she is a Brentwood.
The Brentwood's are the world's most powerful magic wielders who are truly in a league of their own.
They also are famed for only ever having boys.
Not a single female born to their bloodline since the dawn of their beginnings.
Their beginning which was marred by a tale that has followed them for centuries, but which over time was detached from their family, and became just another campfire story.
The tale of the Last Siren, is no mere tale, and she is the omen daughter the siren promised would come with her final breath.
Or so they tell her.
Between the Magicae Council, the Brentwoods, and the ever shady Arcana, she must decide her destiny.
Though only one option seems to be available...
Wreak bloody havoc on the family who created her.
