I picked this book up on the recommendation of a friend. It’s unusual. The first half is a set of imagined vignettes of the monks’ lives on Skellig Michael from its founding (circa 6th c) to eventual abandonment (circa 13th c). The second half is a set of non-fiction chapters about various aspects of early Irish history.
The whole book is well worth a look, although it’s good to remember that in the fifteen years since it was published, a fair amount of historical and archeological research has been done, some of which calls into question elements of the non-fiction chapters. For instance, the idea that anyone was wearing kilts (p. 205)this early in Irish (or Scottish) history has been reconsidered. Even so, it’s an accessible, intriguing entrypoint to the time period and culture.
