The wages of sin is death. It sounds like a scene from a horror movie. But the carnage left by a literal axe murderer in the small town of Little Clementine is far too real. Two families gruesomely slaughtered, two days apart, the only survivor a two-year-old girl. The tight-knit community in the Allegheny Mountains is known for its religious fanaticism and aversion to the government. But without a police force, the sheriff has no choice but to begrudgingly accept the assistance of FBI’s Washington, D.C. Violent Crimes Unit to solve the grisly case. The brutality of the murders suggests the killer is one of the town’s own—and these slayings were as personal as they were violent. But the residents of Little Clementine only take their problems to the Lord or their pastor, and neither are talking. With no fingerprints, evidence, DNA, or leads, Special Agent Emma Last almost wishes for the appearance of the ghosts she can suddenly see to provide a clue. Because the murderer is the proverbial wolf in sheep’s clothing, and the whole flock is in danger. Last Vendetta, the second book in the riveting new FBI mystery series from bestselling author Mary Stone, peels back the veneer of small-town life to expose its terrifying underbelly. Brace yourself to confront the unsettling truth... while the Bible claims, "Vengeance is mine," there are those who disagree.

Three severed heads. Two worlds. One forbidden love. Decapitated bodies seem to be following Special Agent Emma Last. First, it was the haunting appearance of the ghost of Ned, the late brother of Emma’s friend and colleague, who was beheaded in a car accident years ago. Now, D.C.’s Violent Crimes Unit has two more headless victims. Or is it four? Over two eerie nights, a crypt raider exchanged ancient skeletal skulls for the freshly severed heads of two unidentified men. Yet, the whereabouts of their bodies and the stolen bones remain shrouded in mystery. The why behind the seemingly ritualist crimes is even more perplexing. The victims have nothing in common other than age and orientation. But without their bodies, the cause of their deaths remains elusive. Could Emma and her team be dealing with some type of dark occult practice? More importantly, is there a method to the killer’s madness? The clock is ticking. And if bad things come in threes, Emma and the team only have one more day to decipher the mind of a killer before they strike again.

Some memories detonate on impact. Fresh from the adrenaline rush of her latest case, FBI Special Agent Emma Last dropped a bombshell on her friend and coworker Mia Logan—she can communicate with ghosts. Worse, one spectral figure is Mia’s brother. And he insists he was murdered. But there's little time to grapple with the supernatural when the Violent Crimes team is thrust into the heart of Randall County, West Virginia where a local diner is reduced to rubble in a powerful explosion. Although the owner and his daughter live above the restaurant, no human remains are found in the rubble. Did they have the motive, or the skill, to make a bomb? Or are they the victims of a more disturbing vendetta? The stakes heighten when another local diner faces the same fate, its owner and his daughter also conspicuously missing. The pattern is undeniable. As a winter storm encroaches, Emma and her team are in a race against time to find the victims before a third explosion blows Randall County apart. Last Chance, the fourth book in the captivating new FBI series by bestselling author Mary Stone, drives home a haunting reality: you don’t need enemies to become a target.

Love’s darkest gift carries a deadly price. There’s nothing like an old-fashioned bank robbery to get the D.C. FBI office moving, even as half the team are sidelined with the flu. But this isn’t a normal heist, and Special Agent Emma Last is no typical FBI operative, something her partner, Leo Ambrose, is quickly realizing. And he doesn’t know the half of it. As Emma struggles with her secret, a masked assailant stages a morning robbery, making off with forty thousand dollars and leaving a trail of chaos in his wake. Beyond the money, he forces the bank manager, a guard, and the only two customers—a mother and her young daughter—into the vault. The loot? A safety deposit box containing nothing more than notebooks. The devastation? He murders the mother after cutting and collecting a lock of her hair. As a gift or a trophy? Upon their arrival, Emma and Leo are thrust into a relentless chase, hot on the robber’s trail. But just like the ghosts that haunt Emma, he vanishes into thin air. As the team tracks down one dead end after another, they discover this wasn’t the perp’s first heist. Or his first act of murder.

It’s a bad day when blood and death is easier to discuss than the truth. A bar owner and a bartender, embroiled in a secret affair, are found shot execution style shortly after closing time. Security footage reveals the perp forcing his victims to their knees before taking their lives. With only a Bible verse left behind, the religious undertone is unmistakable. Another zealot making an entire faith look bad. The message is impersonal, self-righteous...and indicates the killer isn’t done. Now Emma and the rest of the team must find him before he leaves his next blood-spattered clue. When the gunman’s signature is found at a nearby mosque, Emma thinks he’s marked his next location. Her hunch proves wrong, though, and he had a different location in mind, executing two more victims. With a body count of four in just a day, the urgency escalates. As this killer becomes more unhinged, nothing can prepare Emma for who and where he strikes next. Last Sinner is the sixth book in the Emma Last series by bestselling author Mary Stone. As the pages turn, prepare to pray for mercy.
