Ash and Sand is an award-winning indie grimdark fantasy trilogy by Richard Nell, following two protagonists across two very different worlds: Ruka, a deformed genius outcast in the frozen wastes of the Ascom, consumed by vengeance and carrying a dark twin within him; and Kale, a wastrel island prince forcing himself to grow up in the cruelty of military service.

Across three richly constructed books, their fates collide in a story of brutal coming-of-age, complex moral politics, and the question of what kind of world rises from the ruins of the old. Compared by readers to Joe Abercrombie and George R.R. Martin, with an emotional intelligence that is entirely its own.
