Books Like Scion

by James Islington

Scion is built around one clear engine: a contract killer who must protect a scientist from assassination — and discovers he himself becomes a target. James Islington pushes the story at thriller speed, layering close-quarters action, assassins' tradecraft and tightening conspiratorial reveals. The novel trades the long arcs and secondary-world trappings of his earlier epic fantasy for lean, propulsive near-future plotting where every scene has stakes and every alliance can flip.

If you picked Scion for the relentless pace, the protector/assassin paradox, the twist-heavy conspiracy, or the moral friction of violence and duty, you’ll want different things from your next read. Some of the books below echo Scion’s hard-edged noir and hired-gun viewpoint; others match its tech-led paranoia or its take-no-prisoners plotting. I’ve made clear which element each title shares so you can pick the book that scratches the same itch — whether that’s taut action, speculative tech implications, or a protagonist who has to choose between killing and keeping someone alive.

About Scion

Published 1 September 2026, Scion is James Islington’s first deliberate move away from secondary-world epic fantasy into science-fiction thriller territory. It centers on a contract killer assigned to protect a scientist and escalates into a wider conspiracy; it is the first book in a planned series.

Frequently asked questions

What should I read after Scion if I want more assassin-versus-protector tension?+

Try The Bourne Identity or The Trinity Game — both foreground a professional killer navigating duplicity while forced into roles that complicate their trade. The Bourne Identity is closer to Scion’s kinetic espionage, while The Trinity Game shares layered political-tech intrigue.

Which book here matches Scion’s near-future tech and moral questions about violence?+

Altered Carbon and Kill Decision are the best fits. Altered Carbon pairs a hard-edged, hired-gun POV with speculative tech; Kill Decision foregrounds emergent weapon tech and the ethical fallout of autonomous systems.

I liked Islington’s epic fantasy — will I find similar scope here?+

Scion is intentionally narrower in scope and contemporary in setup than The Will of the Many and The Strength of the Few. If you want wider military or political canvases reminiscent of epic stakes, The Risen Empire and 2034: A Novel of the Next War provide broader geopolitical backdrops while staying in the realm of near-future conflict.

Is Scion more thriller or science fiction?+

It’s a science-fiction thriller: the narrative drive and structure are thriller-first (propulsive pacing, assassination plots) while speculative elements and tech paranoia shape its conspiratorial stakes.
