After surviving the fallout of Blitzø's near-execution, IMP is left bruised, fractured, and trying to figure out what comes next. But peace doesn't last long. A mysterious two-million-dollar contract draws the team into Envy, where a string of disappearances, brutal killings, and a terrifying hidden enemy push them deeper into a case none of them fully understand.

Still reeling from the aftermath of the trial and the violence in Envy, IMP finds itself pulled deeper into a mystery surrounding a supposedly extinct species, a secretive family of assassins, and a history Hell would rather keep buried.

I.M.P. has work to do.
