An Impressive Feat of World-Building…

“Rockall is one of the most significant achievements in the history of fantasy worldbuilding, and *William Sarjeant was a true Renaissance Man. It’s wonderful to see his vast creation being given new life, and being brought to new audiences.”
— Robert J. Sawyer, Hugo Award-winning author of The Oppenheimer Alternative
“*William Sarjeant’s Rockall series is an impressive feat of world-building and story-telling. Mark Sebanc’s thoughtful re-framing of these works makes them more accessible to a new generation of readers. I welcome this well-deserved re-emergence of Sarjeant’s remarkable work.”
— Douglas A. Anderson, editor of The Annotated Hobbit
* A world-renowned scholar, William Sarjeant used the pen name Antony Swithin.

And there begin adventures stranger than the wildest of Simon’s imaginings; adventures that will change the course of his life and reshape that land for ever…
