I heard a lot of good things about this series and I must say it absolutely lives up to the hype. I think it's my favourite installment in the Percy Jackson universe thus far!

I find that Rick Riordan's books sometimes suffer a bit from episodic storytelling, wherein the characters get a quest but then keep encountering sidequests/minibosses along the way, which sometimes has me a bit tired whenever they encounter yet another obstacle they must cleverly defeat. This book, I feel, balances that really well with progressing the actual main plot, and I wasn't bored for a single second. 

I also loved Apollo as a narrator. I really dig somewhat unlikable characters, and Apollo is just perfect for me. He's quite arrogant but written in a way that's really entertaining, and ultimately very lovable, and I found myself really rooting for him.

I look forward to the rest of this series!
