Scorpion

More about the book

All over the world, random people are being brutally assassinated. Each death is unique, but all have one thing in common- four numbers branded or carved into the victims' flesh. What does it mean? For the brilliant and haunted CIA analyst Quinn Mitchell, it means leaving a safe and predictable desk job to track down a global serial killer. What she doesn't know is that nothing about this mission - her handlers, the intelligence, even the laws of cause and effect - can be trusted. And her target has saved his most shocking murder for last . . .
