#1 New York Times best-selling author Claudia Gray extends the story of The X-Files beyond its eleventh season into thrilling new territory!

Fox Mulder and Dana Scully are still reeling from the death of their son William as they struggle to find purpose away from the X-Files. Though their current relationship is tenuous, they hope to seize their second chance to be a family, despite the many questions surrounding Scully's pregnancy.

Then the FBI asks for their help on a case that hits all too close to home: a serial killer in the Washington, DC area who targets pregnant women. The killer appears to possess a mysterious, uncanny power over electricity, which is enough for the Bureau to re-open the X-Files--if Mulder and Scully are willing.

They cautiously agree, concerned about the safety of their own unborn child yet committed to finding justice for the killer's victims. But their return to the FBI sparks the interest of a shadowy cabal, the heirs to the now-dead Syndicate, and Mulder and Scully soon discover that what at first seems to be just another X-File is connected to a worldwide threat on an unprecedented scale . . . one with their own future at its heart.
