Wow, read them both (the book I should finish by this sunday) but they're both awesome!!!! Of course as Pendragon nerds u may notice some MINOR things in the graphic novel but still it was preety awesome, and one more thing, if u haven't read The Merchant Of Death then u may not understand some things in the graphic novel (they didnt have much space so they tried to cover so much in so little that they skip details) but it's pretty awesome!!!!

Even better with the book 9, it is just so AWESOME, there is so much happening u just get hyped!!!!!!
