One-Eyed Jacks — George R.R. Martin

Something is stirring on Ellis Island, something strange and dangerous enough to subdue even the white-hot tensions between Wild Cards and naturals. The Jumpers are rising....

The members of this vicious gang have the power to jump their minds into others' bodies, use them to commit acts of terror and violence--then withdraw as quickly as they came, leaving their hapless victims to face the consequences. Not even the powerful Aces are immune to the Jumper threat.
