Enraged By Magic by E. M. Moore

Hate consumes love.
At least that’s what the demon would like Norah and her coven to think.
After seeing his old friend, Travis reverts to his former self. Norah knows, though, that now more than ever, they need to become one if they’re to defeat their enemy. The only thing the coven has to do is get Travis on board the demon-slaying train…and fast.
Now that his identity was revealed, the demon has turned his hate on all of Salem, destroying things and people at will. The more anger and fear he spews, the coven realizes they can’t do the job themselves. This is a job for all the magical people of Salem.
With help from friends and frenemies—and Norah’s magical element—they embark on a fight for their lives in this finale to the Order of the Akasha series. Like Granny says, “Pure will always win.” But is it pure hate, or pure love?
