After the Vampire Magician’s attempt to free Lucifer in Chicago, the Ancients are on their way to Thermopolis, Wyoming, to hold the Vampire Sheriff accountable. During the battle of Chicago, the demon Legion escaped from Hell and is determined to open Hell's Gates.
Young men are disappearing in Chicago, and the vampire sheriff has asked for Sam Harlan's help. With Sister Callie Calahane by his side, Sam will push himself to the limit to find out what happened to the missing men - even if it means dealing with the devil.
The Office of Threat Management watches over the world, but super-soldier John Frist is exhausted. When the OTM sends him to Switzerland, it seems too good to be true. It is. The OTM's contact has been murdered, and John and his teammates become the focus of a manhunt that forces them deep underground. OTM Director Eric Wise suspects the hacking collective Digital Freedom Alliance might be behind it, but why would a group of hackers be so desperate to out a covert American military group? Unfortunately, Eric has more on his hands.
John Frist was a soldier, a hero, and the victim of an IED attack in Iraq before his discharge. He returned home and committed a terrible act of domestic terrorism. Transformed by the StrikeForce technology, he saved New York City from a dirty bomb and nearly died in the process. For him, the ensuing two years has been a bone-wearying series of battles to protect the United States. Eric Wise has risen from Director of Project StrikeForce to Assistant Director of the Office of Threat Management.
"Vampires. They're everywhere. It's my job to stop them. A woman is missing. Hell, isn't there always? The church thinks a vampire is involved, but it's much worse than that. Much worse. Witches. Why did it have to be witches?" - Sam Harlan
John Frist was a good soldier, until his Humvee was hit by an IED in Iraq. Discharged, he carries out one of the worst terror attacks in US history. Captured and brainwashed, he is remade by Project StrikeForce into a technologically enhanced super-soldier. Now he must find a former Mujahideen, Abdullah the Bomber, before Abdullah can strike the US with a terror attack of his own. Eric Wise, a former Delta Force operator, is tasked with training Frist.
Six weeks since discovering the truth behind his family legacy, Sam Harlan has worked with Sister Callie Calahane to learn how to kill vampires, desperate to make them pay. The woman's voice on the answering machine was intriguing. “Jack, it's Mary Kate. I've got your newest order and.... I need to talk.” Jack Harlan, the legendary vampire killer, was Sam's distant relative, but Jack Harlan was dead. Sam had seen to it himself.
Until he met vampire hunter Jack Harlan, Sam Fisher lived a quiet, peaceful life. Now that dark creatures have murdered his wife and kidnapped his daughter, Sam must learn everything he can from his new mentor to find his little girl, before it is too late.
