In Memoriam is set in the near future. Whilst humanity was busy uploading photos to the cloud and digitising every book ever written, the human brain was quietly evolving, and we lost the capacity to store long-term memory. But Britain's National Health Service developed the cure: a government-issued memory chip. When 17-year-old Somalia finds her mum dead on their living room floor, she makes an unprecedented, and criminal, decision to implant her mother's memory chip. Somalia's search for identity sends her spiraling into an underground world of digital militants and authoritarian dispute, until she finds herself at the heart of a conspiracy; one that will unite her mother's past and the dark origins of this scientific breakthrough.
