Amazing just amazing. The perfect end to just an amazing series. The characters developed wonderfully. I'm so happy about the way the ending went down and the book kept me on my toes. I would have wanted POV from some of the other characters we didn't get much on like Percy and Annabeth, but I'm so happy with what we got. My love for Piper grew even more. She is still my main girl and my favourite character. I grew super attached to Nico and Reyna. Just so good! So good!
