While hurtling through space on a mysterious trip to the farthest reaches of the universe, Peg recounts a lifetime of events that led her to this moment.

A young man, Otto, searches for an old man, Stuart, who is believed to be suffering from dementia. Otto provides Stuart a means to regain his memory: memory implants that Otto procured on the black market. As Stuart's memory regenerates, we begin to question Otto's motives and uncover a shocking truth about Stuart's identity — a truth that reverberates throughout all seven stories of the series.
