This is one of those books that I probably should’ve re-read the entire series before reading. So much has happened in the novels, especially if you go all the way back to the first Percy Jackson book, but even just within the five books of this series it’s been a long journey.
As much as I want to say this was the best book in the series, I honestly think The House of Hades was better. And this is for a couple of reasons. If possible The Blood of Olympus had TOO much action. I get that this is the end of a series which is a spin-off/second half of another series, but this book just didn’t stop with the epic battles. Sure they’re facing the end of the world and Riordan said it best,
“Today, one way or another, their journey would end.” (378)
But honestly, the book left me exhausted and not in a good way. It felt like there was so much that happened off the page that I couldn’t keep track of who was where and what was happening. There are spoilers to the series and this book so don’t read past here if you’re planning to read it.
This book has been on my to-be-read shelf for so long it took quite a while to trace where and when I bought it! I apparently picked it up way back in 
I did it. I completed a John Steinbeck novel!
