Alex Benedict receives a cryptic message asking for help from celebrated writer Vicki Greene, who then voluntarily has her memory erased. She has no memory of her past life, or even of her plea for assistance. But she has transferred an enormous sum of money to Alex, also without explanation.

The answers to this mystery lie on the most remote of human worlds. There Alex and his pilot companion, Chase Kolpath, will uncover a secret connected to a decades-old political upheaval, a secret that somebody desperately wants hidden, though the price of that silence is unimaginable.
