*Spoilers!* *Sorry for my English! English isn’t my native language* Who will die in the Blood of Olympus? And what do bạn think about my theory?

I suddenly realised something! The Mất tích Hero is about Jason, The Son of Neptune is about Percy, The Sign of Athena is about Annabeth and The House of Hades is about Hazel. There are 7 Giải cứu thế giới and 5 books. A girl and a boy will die! So we maybe will find out who will die in the last book in the first chapter!
If the first chapter of Blood Olympus starts with Leo hoặc Frank, then there is a change that Piper and Frank/Leo (depends on with who we start) are going to die! What do bạn think about this theory? Who will die? Who will survive?
We shall see in the Blood of Olympus!
