If you enjoyed Jack Randall's gritty, ambiguous morality as he navigates a world of exploitation and violence in Spares, then you'll be drawn to Takeshi Kovacs in Altered Carbon. Like Randall, Kovacs is a haunted anti-hero whose choices are never black and white, and the story plunges you into a noir-tinged future where right and wrong are constantly shifting.

If the strange, immersive cityscape and surreal underworld in Spares fascinated you, Neverwhere will sweep you into an equally vivid and bizarre London Below. Gaiman crafts a unique urban landscape full of bizarre characters and unsettling dangers, echoing the eerie, detailed worldbuilding you loved.

If you loved the shocking revelations and curveballs in Spares, you'll be hooked by The Demolished Man. Bester's classic is packed with twists, as police Prefect Lincoln Powell chases a murderer in a future where telepathy is the norm—nothing is ever as it seems, and surprises lurk around every corner.

If you appreciated the grim tone and splashes of morbid wit in Spares, Gun, with Occasional Music delivers a hard-boiled detective story in a dystopian future where evolved animals and bizarre drugs are the norm. Lethem's world is violent and strange, but laced with the same sardonic edge.

If you liked the quick pacing and wild, darkly funny narrative voice in Spares, The Gone-Away World is a rollercoaster of bizarre situations and razor-sharp wit. Harkaway's story barrels from one wild set piece to another, all while delivering the kind of bleak humor and energy you enjoyed.
