Brink of Madness

In a future where the Central Intelligence Bureau holds the line between order and chaos, Agent Pell is the agency's most unorthodox weapon. He trusts his hunches more than their computers, and in the deadly game of Cold War espionage, that instinct might be the only thing keeping him alive. When a routine investigation spirals into something far more sinister, Pell finds himself on the trail of an enemy that doesn't just want him dead, they want inside his head. The threat is psychological, the stakes are existential, and the only thing standing between humanity and the brink of madness is one agent's ability to think clearly when everything around him is designed to make him lose his mind. Sheldon builds tension like a pressure cooker, layering paranoia and betrayal against a backdrop of futuristic espionage that feels startlingly prescient. This is vintage 1950s science fiction at its finest: lean, mean, and terrifyingly plausible.
