I don't want to admit it, but it's a disappointment. 
 Like some people were saying, Magnus just reminded me so much of Percy's character, especially his humor; it's like they're the same person, but different situation/family whatever. It was just excruciatingly painful just reading - more like plowing - this book. I even thought about DNFing it. 
 As for the take on the Norse mythology, I was really fucking excited for it. It was different, but it didn't really feel different. Partly because of - yes, you guessed it - give it up for, Magnus Chase! It would've been so, so, so much better if his character weren't so much like Percy. And the other part is how the plot is predictable. It's funny, the details of the book aren't predictable, but the plot is, even the characters. 
 If I had to say anything great about this book, it's...Well, if you're okay with another copy of Percy in another different mythology, then you will love this. The really great parts in this book were how Rick Riordan included the Gods and the Worlds in general; it just damn entertaining. 
 I absolutely have no idea if I will continue this series.
