Witch Wars by Fiona Starr

They say the truth will set you free… but I’m not so sure about that.
Between the vampire who is still very much a threat, to the explosive secret of my origin, and the fact that destroying the Vessel of Truth doesn’t seem to have stopped any of the evil it spawned, I’m beginning to think that maybe freedom isn’t all it’s cracked up to be.
I am more tightly bound than I have ever been in my life, and yet…
Angus and Marco are more than a dream. But I don’t have to pinch myself to know that it’s real. One look at Van’s face is all it takes to see the torment we’re causing him. If something doesn’t give, I am afraid the bond between these brothers, which has endured two centuries of strife and pain will shatter, severing their tie forever.
They say good things come in threes, and looking at my wolves, I sure hope they’re right.
