"Cross-genre brilliance from the superbly talented Nick Harkaway." --William Gibson, New York Times best-selling author of Agency

Cal Sounder is a detective working for the police on certain very sensitive cases. So when he's called in to investigate a homicide at a local apartment, he's surprised by the routineness of it all. But when he arrives on scene, Cal soon learns that the victim--Roddy Tebbit, an otherwise milquetoast techie--is well over seven feet tall. And although he doesn't look a day over thirty, he is ninety-one years old. Tebbit is a Titan--one of this dystopian, near-future society's genetically altered elites. And this case is definitely Cal's thing.

There are only a few thousand Titans worldwide, thanks to Stefan Tonfamecasca's discovery of the controversial T7 genetic therapy, which elevated his family to godlike status. T7 turns average humans into near-immortal distortions of themselves--with immense physical proportions to match their ostentatious, unreachable lifestyles. A dead Titan is big news . . . a murdered Titan is unimaginable. But these modified magnates are Cal's specialty. In fact, his own ex-girlfriend, Athena, is a Titan. And not just any--she is Stefan's daughter, heir to the massive Tonfamecasca empire.

As the murder investigation intensifies, Cal begins to unravel the complicated threads of what should have been a straightforward case, and it becomes clear he's on the trail of a crime whose roots run deep into the dark heart of the world.
