The Circumference Of The World by Lavie Tidhar

A grieving woman searches the shadowy world of rare-book dealers, collectors, and cultists for her missing husband, whose obsession with an elusive pulp science fiction novel may have swallowed him whole. Her quest draws in a hustler with a nose for lost texts and a ruthless collector, while interleaved stories and fragments of the fabled book itself blur boundaries between authorship and myth. Part literary mystery and part speculative noir, it becomes a meditation on love, grief, and the dangerous gravity of stories.
