Neal Asher - Gridlinked: Agent Cormac #1
Gridlinked is a science fiction adventure in the classic, fast-paced, action-packed tradition of Harry Harrison and Poul Anderson, with a dash of cyberpunk and a splash of Ian Fleming added to spice the mix.
Cormac is a legendary Earth Central Security agent, the James Bond of a wealthy future where "runcible" (matter transmitters controlled by AIs) allow interstellar travel in an eye blink throughout the settled worlds of the Polity. Unfortunately, Cormac is nearly burnt out, "grid linked" to the AI net so long that his humanity has begun to drain away. He has to take the cold-turkey cure and shake his addiction to having his brain on the net.
Now he must do without just as he's sent to investigate the unique runcible disaster that's wiped out the entire human colony on planet Samarkand in a thirty-megaton explosion. With the runcible out, Cormac must get there by ship, but he has incurred the wrath of a vicious psychopath called Arian Pelter, who now follows him across the galaxy with a terrifying psychotic killer android in tow. And deep beneath Samarkand's surface there are buried mysteries, fiercely guarded.
