When a serial killer joins the FBI, criminals had better watch out.

Infamous serial killer Francis Ackerman Jr. hasn't lost his macabre tastes. He's just changed sides.

Working for a highly secretive division of the FBI, Ackerman is helping the Bureau track down the most dangerous murderers currently active in the United States.

His first assignment is 'The Alien', a killer whose MO is leaving mutilated bodies in highly intricate crop circles. The Alien has just kidnapped a world-famous expert on extraterrestrials, and if they don't want to find another mangled corpse, Ackerman and his partner, FBI Agent Nadia Shirazi, will have to work fast.

But the Alien's lust for killing seems to surpass even Ackerman's own. Can he track down his target in time... and will he be able to resist the chance to deliver his own macabre form of justice?

The start of a new chapter in the critically acclaimed Ackerman Thrillers, featuring Ackerman and FBI Agent Shirazi hunting down some of the worst killers in modern America.
