In a city plagued by amnesia, Antoine's powers of memory earn him a comfortable living as a prompter to the rich and powerful, who are slowly losing their minds. He knows his time of privilege is short. Amnesia is contagious and growing in virulence. Complicating matters, someone is altering history books and tampering with archives, so that even healthy citizens no longer have an accurate record of the past. When a shady government agent asks Antoine to feed scripted lies to his clients instead of their own true memories, he is faced with a dilemma. An amnesia cure has been found and Antoine can have it if he'll play the government's disinformation game and help change humanity's understanding of their shared past. The alternative is the slow erasure of his lifestyle, his memories, and ultimately himself.
