On a scale of 1 to 10, there seem to be a LOT of similarities between these two series of books.
Let me be clear. I do not mean to denigrate, descry or besmirch Rick Riordan’s books (the first of which came out after the first book in the HP series) in any way. I love the Percy Jackson and the Olympians stories; Greek mythology has been a fascination of mine since I was eleven years old. I think he’s brilliant, and that it’s a wonderful anthology of original, wonderful books.
That being said, there are a very large number of corollaries between the books. Let me elucidate:
- Harry = Percy
- Harry starts preteen = Percy starts preteen
- Harry ages 1 year per book = Percy ages 1 year per book (more or less)
- Hermione = Annabeth
- Ron = Grover
- Dumbledore = Chiron
- Mr. D = Snape
- Fudge = Zeus
- Malfoy = Luke
- Voldemort = Chronos
- Voldemort gets a body in book 4 = Chronos gets a body in book 4
- Harry’s hair won’t stay flat = Percy’s hair won’t stay flat*
- Malfoy starts to look weak, wasted and used late in book 6 (being used by Voldemort) = Luke starts to look weak and used late in book 4 (being used by Chronos)
*Sea Of Monsters (Book 2) on Circe’s Island, Percy is frustrated that his hair never lies flat = Harry’s discomfiture that his own unruly hair will never lie flat (throughout the HP series)
