A terrorist attack pulls former detective Marvin Hale back into space investigations.

In a colonized Solar System where genetic modification has split humanity into Sapiens and Homs, Marvin is recalled to investigate a chain of attacks that threatens the balance between Earth's governments. Aboard the cargo ship Blue Whale, with a crew of outcasts, he follows a thread that ties political conspiracies to forbidden experiments. The trail leads to a threat at the edge of the Solar System, beyond politics and beyond technology.
