Faller

When the book opens, the entire population has lost its memory, including personal identities, relatives, companions, and the ability to read. The world has broken apart into rocky fragments drifting through an empty sky. Whatever food, water, and power remain must be scavenged, and very little turns up.

The protagonist, Faller, carries three odd items: a snapshot of himself with a woman he cannot recall, a small toy soldier fitted with a parachute, and a map sketched in blood. Relying only on these, he jumps from the edge of his island into the void, determined to find her and repair what has gone wrong.

His journey takes him to other floating islands and to unsettling duplicates of himself and of other people. He also discovers that one man holds a deep grudge against him, rooted in deeds Faller has no memory of committing.
