Sebastien De Castell


Canada

Sebastien de Castell had just finished a degree in Archaeology when he started work on his first dig. Four hours later he realized how much he actually hated archaeology and left to pursue a very focused career as a musician, ombudsman, interaction designer, fight choreographer, teacher, project manager, actor, and product strategist. His only defence against the charge of unbridled dilettantism is that he genuinely likes doing these things and that, in one way or another, each of these fields plays a role in his writing. He sternly resists the accusation of being a Renaissance Man in the hopes that more people will label him that way.

Sebastien lives in Vancouver, Canada with his lovely wife and two belligerent cats.

The Silverblood Promise (2024)
(Last Legacy , book 1)
James Logan
"An engrossing fantasy romp full of endearing characters, The Silverblood Promise is full of unexpected twists and turns, and an optimistic spirit. Relentlessly entertaining, defiantly idealistic, it's a daring debut filled to the brim with classic fantasy fun."
thumb
The Burning Land (2024)
(Talmont Trilogy, book 1)
David Hair
"A riveting, thoughtful fantasy that blends the best of Guy Gavriel Kay and Brandon Sanderson, set in a richly textured landscape where battle-hardened heroes confront their most dangerous enemy: the truth about the nature of their heroism and what the magic they rely upon costs the world around them. Full of nuanced, loveable characters whose complex relationships with each other and with themselves make The Burning Landa compulsively readable adventure not to be missed!"
