The Darketo Sanction is where the government hides its mad scientists.
Which is exactly the kind of place private investigator Alex Cheradon tries very hard to avoid.
Unfortunately, a missing scientist leads Alex straight to the heart of the Darketo Sanction. He soon finds himself in the middle of experimental technologies, genius-level egos, and a security system run by a mysterious hybrid intelligence called Cassandra-a system so advanced it can monitor nearly everything happening inside the facility.
There's just one problem.
The last time Cassandra made a mistake, it nearly killed everyone in the building.
Now Alex is trapped in a skyscraper full of paranoid scientists, unstable experiments, and secrets powerful people would kill to keep buried.
And if Cassandra's calculations are wrong again...
The next "statistical anomaly" might wipe out the entire city.
