The Fourth Ambit

When Gilles can't control his addiction to online stimulants, he loses his graduate school appointment and his access to the Ambit. Poverty and a life of pointless toil seem to be his destiny, but when he stumbles upon one of his professors in a seedy bar, Gilles' fortunes shift. In his haste to leave, the professor drops three gold UNI cards he'd been about to sell on the black market.

Gilles takes the cards and uses them to regain access to the Ambit. What Gilles didn't count on, however, was the fact that the owner of the UNI cards, Facia Corporation, had put them on the black market for a purpose. Gilles becomes their newest recruit, and an unwilling Ambit tracker.
