Someone is hunting the hunters. Can Travis and Brent stop the monsters and figure out what's behind the attacks before it's too late? When ex-priest Travis Dominick and former-FBI-agent-turned-private-investigator Brent Lawson investigate a series of dangerous hauntings, they discover that something is powering up old ghosts and adding mojo to the monsters. The Sinistram seems to be at the heart of the situation, a secretive order of warrior priests sworn to fight supernatural threats. Travis left the Sinistram years ago because of the organization's corruption and double standards. Now the group's arcane knowledge and dangerous secrets might hold the key to stopping the hauntings, but help might come at too high a price. As the mystery unravels, Travis and Brent navigate a dangerous maze of betrayals and conflicting alliances, risking everything to uncover a supernatural cover-up that could change the balance of power between mortals and immortals forever. Sinistram is a dark urban fantasy thrill ride filled with legends and lore, forbidden magic, vengeful ghosts, secret government agencies, Vatican ninja-priests, found family, hidden libraries, psychics, mediums, witches, supernatural creatures, and an unshakable bond of friendship.
