Amahle is the captain and sole occupant of the starship Mnemosyne. She is a “light chaser”, travelling on a thousand-year loop to inhabited star systems, the scattered colonies of humanity. She brings “memory collars”, to be worn by selected people and their descendants, until she returns on her next loop to collect them. These gather the life experiences of the wearers for her employers at the end of the loop to enjoy as entertainment. The human worlds are at varying degrees of technological development, but societies seem oddly stable, to the point of stagnation. It eventually dawns on Amahle that things are not as idyllic as they seem.
The premise is clever, intriguing, and novel. The novella format suits it perfectly. Amahle is excuisitely characterised as an aloof de facto demigoddess who slowly realises the truth about her existence. Her sense of betrayal is palpable and visceral. The story is not overlong, and superbly edited to maintain momentum.
