Decent read, but not worth buying
Reviewed in the United States on October 6, 2018
I'm a huge fan of all five of Riordan's mythological series, and most of his supplementary works to those story lines, but I'm a bit disappointed in this one. Riordan left some threads for future Magnus Chase adventures at the end of the last novel (like sitting on Hlidskalf someday), so I was expecting some good adventures, like the short stories written for Percy Jackson which added or picked up threads from those novels. Disappointingly, except for a name drop, Magnus isn't even IN these stories! Each of these stories is told from the perspective of a different character in the series, from Odin to Amir (good move); they're entertaining, but very short (I read the whole book in less than 2 hours) and really add nothing to the characters or the Norse world story lines.
Bottom line: worth picking up at the library, but don't waste your money buying it.
