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 is surprised at first to see that the victim appears to be a rather typical techie. But on closer inspection, he finds the victim is over seven feet tall. And even though he doesn't look a day over thirty, he is actually ninety years old. Clearly, he is a Titan - one of this dystopian, near-future society's genetically-altered elites. There are only a few thousand Titans worldwide, all thanks to Stefan Tonfamecasca's discovery of the controversial T7 genetic therapy, which elevated his family to near godlike status. A dead Titan is big news - a murdered Titan is unimaginable. But Titans are Cal's specialty. In fact, his ex-girlfriend, Athena, is a Titan. And not just any Titan - she's Stefan's daughter, heir to the Tonfamecasca empire.
