HAHA!Y would u even attempt 2 even ask that question?
Harry Potter is one of the best series ever written and has sold millions of copies in over 60 languages.
Even though the Percy Jackson series is pretty good,it could never replace Harry Potter,or even 4 that matter,y would u combine them?There 2 different things.
And besides,the casting for Harry Potter was much,much better than the castin 4 the Lightning Thief.I mean,who can puncak, atas Alan Rickman,or Helena Bonham Carter?Logan Lerman o please,compared 2 those actors,he is just another nobody.
Both authors r great,but,Jo was better.She gave the series ups and down no one would ever expect.The film would b different 2 ( and the directors wont mix 2 buku 2 create a lebih exciting movie )
Anyway,no,i do not think that they should b combined.
