Concluding the Chronicles of Prydain series, this final book sees the last prophecy made by Hen Wen unfold as the mighty sword Dyrnwyn loses its power and is lost, and the companions set out to gather an army from all across Prydain in order to finally confront Arawn Death-Lord once and for all. Basically everyone from the previous books shows up in this final conclusion, and at the end of it all there's a prophecy fulfilled and a new High King in Prydain.

Still very YA so a super quick read, but a satisfying conclusion that wraps up all the loose ends.
