The House of Hades
Oh My Effin God, this book was amazing. I loved the ending fight with Frank, Jason, Piper, and Nico. I was playing the song Battle Scars with that part and it made the part seem so real. And I was crying on and off during the elevator scene and at the end when Percy says to the stars that Bob says hi. I am even crying now typing this up. In my opinion this is the best of all the Rick Riordan books. You will love it as much as I do.
