House of Gaian 

the battle reaches its stunning conclusion in this final volume of the tir Alainn trilogy. With the eastern barons under his control and a growing army of black-cloaked torturers, Adolfo is headed toward the Mother’s Hills – the wellspring of magic in Sylvalan, as well as home to the reclusive witches of the House of Gaian. As the battle to end all battles looms closer, normal humans and witches are forced to join ranks with the Fae, the beautiful, powerful, and arrogant race that inhabits the magical realm of tir Alainn.But the witches are faced with a crisis: if they are to fight the Black Coats, they’ll have to break their sacred creed of ‘Do No Harm’. And to make matters worse, the Master Inquisitor has a host of nasty surprises in store, including a new way to create a limitless army of nighthunters, virtually unstoppable soul-eating creatures of darkness.
