The First Witch-Mage

Those who cross a Blackwood soon learn that they won't
like the results.
Theadora Kathryn Blackwood's life is just the way she wants
it. Thea focuses on what she wants to do, what she wants to study, and the
local COVEN hierarchy leaves her the hell alone.
It took years for her to accomplish that much freedom, and
now she is about to graduate college, the local coven leader has given her what
she wants most.
The opportunity to be freed from the shackles of Coven
Politics for the rest of her life.

The catch is that she must join the Arcane Investigations Division as an
Arcane Consultant for three years.
If Thea is still employed at the end of the set time, the
Coven will absolve her of all ties and responsibility to them.
The downside is that NOLA AID has lost two witches in the
last four years. No one expects an untrained witch without the Coven's support
to survive.

Even if she is a Blackwood.
