Autumn Visits is a science fiction novel by Russian writer Sergey Lukyanenko, published in 1997 in book form.

The Original for this Envoy is a female doctor, who has seen the consequences of love, kindness and compassion neglected in her patients dying without access to medicines and treatments.

The force of Knowledge would create a better, more reasonable world, but is hampered by physical fraility, and always ends up subjugated by power.

The Envoy of knowledge would change that, but his Original is an old scientist suffering from terminal cancer, who is intelligent and wise, but physically impotent.

Power represents a strong state, claiming people's loyalty, guiding their lives, and focusing their strength on a single purpose, but also punishing individual action, turning people into a herd being driven by a stern and beloved shepherd.

Growth is, appropriately, represented by a teenager—a somewhat dour and cynical boy, who is implied to have lost his faith in the world.

This Envoy and his Original begin to grow apart as the novel progresses, diverging, and even spending a lot of time away from each other, unlike most other Envoy/Original pairs.

Unlike the other Envoys, Growth does not remember his past incarnations, as experience would defeat the purpose of growing.
