Both the name given to a trilogy of books written by Peter F Hamilton, and the name of a special Army corps. within the books.

Short version: after a blanket testing for psi powers within the army, those who exhibited some were given an implant which could generate a neurohormone on demand to amplify this power. The corps was later disbanded (since the results weren't predictable), leaving the ex-squaddies to make their way as best they could.

Greg Mandel became a private detective - with an amplified empathic/telepathic ability.

The first book is definitely worth anyone's time to read (as well as being fairly unusual for being largely set in/around Peterborough); the later ones aren't quite so hot, but still very good.

The books are (in order) Mindstar Rising, A Quantum Murder, and The Nano-flower.
