How Castle Federation Began
Glynn Stewart, a Canadian author with a knack for weaving intricate sci-fi worlds, launched the Castle Federation series in 2015 with Space Carrier Avalon. Escaping a dreary future as an accountant, Stewart poured his passion for high-tech futures into this transhumanist space opera. Inspired by classics like David Weber’s Honor Harrington series, he crafted a universe where humanity’s factions—the Terran Commonwealth and the Alliance of Free Stars—clash over ideals of unification versus freedom, set against a backdrop of advanced technology and sprawling star systems.
The Heart of Castle Federation
The series kicks off with Space Carrier Avalon (2015), where Kyle Roberts, a young commander, takes charge of the aging carrier Avalon, only to find himself thrust into a war that could doom the Alliance. In Stellar Fox (2015), Roberts, now dubbed the ‘Stellar Fox,’ navigates treacherous missions and personal baggage as the conflict escalates. Operation Medusa (2017), the sixth book, culminates in a daring, all-or-nothing strike to end the war, showcasing Stewart’s flair for high-stakes drama. The series also includes a prequel novella, A Question of Faith (2020), exploring the Alliance’s origins.
Castle Federation shines with its blend of military tactics, political intrigue, and diverse characters. Themes of duty, sacrifice, and equality resonate in a transhumanist setting where gender and ethnicity are fluid, reflecting a progressive future. Stewart’s detailed world-building, from Alcubierre drives to starfighter dogfights, immerses readers in a universe that feels both futuristic and relatable, drawing comparisons to Battlestar Galactica and Weber’s works.
Why Castle Federation Resonates
The Castle Federation series has carved a niche among space opera fans for its accessible yet intricate storytelling. Its inclusive cast—featuring queer and hermaphrodite characters—mirrors real-world diversity, earning praise for authenticity. While not groundbreaking, Stewart’s ability to deploy genre tropes with finesse keeps readers hooked, with over 2,000 Goodreads ratings averaging 4.38 for Operation Medusa. The series’ self-published roots and expansion to retailers like Kobo highlight its grassroots appeal, making it a beloved gem for military sci-fi enthusiasts.
