Novel: Doc Sidhe

Overview
Doc Sidhe follows Harris Greene, a martial artist and streetwise fighter who stumbles into a hidden boundary between the mundane world and a parallel realm of faerie power. That crossing reveals a city and a people where mythic Sidhe customs and raw, archaic magic coexist uneasily with finds and fragments of human technology. The story moves quickly, blending street-level action with mythic stakes as Harris partners with the enigmatic figure known only as Doc Sidhe.
Allston frames the book as an urban fantasy that leans on action and voice as much as worldbuilding. The tone shifts between gritty, kinetic fight scenes and moments of sly humor and rueful reflection, producing a novel that reads like a collision between a noir martial-arts thriller and a classical fairy tale.

Plot
Harris Greene's discovery of the Sidhe realm is accidental and violent: what begins as a pursuit or scrape in the city tumbles through an otherworldly portal, and Harris finds himself in a place where rules are older and consequences literal. The Sidhe world is not idyllic, its politics are brittle, its magic dangerous, and its contact with human technology has sparked an unstable fusion that threatens to tear both realms apart.
Doc Sidhe, a compelling and inscrutable ally, recruits Harris into a struggle that has political and metaphysical dimensions. Together they confront factions who would exploit the crossworld linkage: technologists who fetishize machinery and magicians who would weaponize ancient rites. Action sequences drive much of the narrative, but each confrontation also tests Harris's sense of honor and identity as he becomes a bridge between two incompatible orders.

Main Characters
Harris Greene is built around physical discipline and blunt moral code. His martial training shapes how he sees threats and settles disputes, and his outsider status makes him both useful and endangered in a society governed by layered, arcane rules. Harris's voice carries the novel, tough, ironic, and candid about violence and consequence.
Doc Sidhe remains a mystery for much of the book: a healer, strategist, and ambiguous emblem of the Sidhe themselves. Other players, power-hungry technomancers, conservative faerie nobles, and human opportunists who traffic in both worlds, populate the story, each complicating the simple binary of "magic versus technology" and ensuring that alliances are fragile and costly.

Themes and Style
At its heart, the book explores collision and compromise: modernity pressed against myth, pragmatic skill pressed against ritual power, and an individual's code pressed against communal fate. Questions of identity and obligation recur as Harris weighs loyalty to his own world against responsibilities that extend into the Sidhe domain. The novel examines how progress and tradition can wound one another when neither yields.
Allston's prose favors momentum and clarity. Fight scenes are choreographed with a cinematic economy, dialogue snaps with tough humor, and descriptions balance enough detail to make the Sidhe uncanny without bogging down the pace. The interplay of speculative ideas, what happens when technologies built for one reality are misapplied in another, gives the action intellectual bite.

Reception and Legacy
Doc Sidhe attracted readers who wanted urban fantasy with a hard-edged action sensibility and those who appreciated cross-genre experimentation. It may not have the mainstream recognition of larger fantasy sagas, but it stands out for marrying martial-arts choreography and faerie lore in a contemporary setting. For fans of brisk, character-driven fantasy that emphasizes conflict and moral ambiguity, the novel remains a distinctive, entertaining read.
The book's strengths lie in its buoyant pacing and the unusual partnership at its center. Harris Greene and Doc Sidhe form an alliance that is as much about survival as it is about negotiating the ethics of two colliding worlds, leaving readers with a story that satisfies both as an adventure and as a reflection on how disparate cultures meet and change one another.
