Okay I found this thing out last night when we were walking in Glorietta and my mom texted me to ask what the title of HP book 7 is.

Here it is,

Book 1: Harry Potter and the Sorcerer's Stone/Philosopher's Stone
Book 2: Harry Potter and the Chamber of Secrets
Book 3: Harry Potter and the Prisoner of Azkaban
Book 4: Harry Potter and the Goblet of Fire
Book 5: Harry Potter and the Order of the Phoenix
Book 6: Harry Potter and the Half-Blood Prince
Book 7: Harry Potter and the Deathly Hallows

Take a look at the bold words I typed. In book four, it is "fire" which is a four-letter word. In book five, it is "order" which is a five-letter word. In Book six, it's "prince" which is a six-letter word. And in book seven, it's both "deathy" and "hallows", and they're both seven-letter words. See?

Maybe in book two it's the word "of". haha. But that won't make any sense at all. But if you find anything that would make the word "of" in book two sensible enough, please email me[the link is at the lower part of my sidebar]. thanks. :)

And in case the word "of" makes sense, what words in books one and two would?
