Witch-Mage Uprising by Isabel Campbell

Things have been quiet in NOLA… Too quiet.

The Coven had thankfully gone back to shunning Thea after the Silas debacle. Unfortunately, the brutal murders of several hedge witches leaves everyone involved with no option.
They must present a united front—with Thea as the liaison between AID and the Coven.
Thea finds motivation in the form of wanting to relieve Jax of the guilt he feels for mentoring the victims.
The investigation opens doors within the Coven for Thea. However distasteful she finds the skeletons in the Coven’s closets, the knowledge she gains could be just what she needs to get to the bottom of the mystery before it’s too late for the unaffiliated witches in the city.
Early leads point to a literal witch hunt. Keeping the peace as tensions rise in the magical community is not conducive to getting the answers every side is demanding.

Solving the murders can’t be as simple as identifying non-magicals taking out a vendetta against the seemingly unprotected witches outside the Coven? Right?
