The story did not make a ton of sense but it was still fun to read. There is little explanation of what most of the Hallows are or what they do, mostly focused on a single one. It is a very violent fantasy tale and follows and extremely similar plot basis as his prior novel "The Hallows" and focuses on the same exact hallow. It does take a turn to a religious focus maybe 3/4 of the way through. The story builds a lot (but is rather repetitive) and then the climax happens pretty quickly, the big event is maybe the last 5% of the book.

After doing my research (as the author's note implies the items are real), I came across an interview that explains the myth/legend from where the hallows are taken. So the welsh mythology is mixed with religion. Very little of the actual welsh mythology is explained, as they make the hybrid with christianity. If you enjoy that type of fantasy with lots of violence then this might be for you.
