What is the best book?[all]

Out of every single book in Riordanverse(not including the short books), what book do you think is the best? As of now, my shortlisted ones are:

• The Last Olympian
• The Lost Hero(don't you dare argue with me)
• The Tower Of Nero
• The Throne Of Fire
• The House Of Hades

Disclaimer: I haven't read Magnus Chase yet

Disclaimer 2: This includes Percy Jackson, Heroes Of Olympus, Trials Of Apollo, The Senior Year Series, The Kane Chronicles, Magnus Chase, Greek Gods and Heroes

Edit: I'M SO HAPPY NO ONE SAID BoO! yet......
