I haven’t read the three books in the Kane Chronicles but I am a Percy Jackson Fan. I found The Son of Sobek to be a Percy Jackson & Kane Chronicles short story mash up – which I quite liked. I needed a quick Percy fix and this did it, even though Carter was the narrator. It’s a fast paced, quick story to read and I would highly recommend it to any Carter Kane or Percy Jackson fan!
Both Carter and Percy can tell that they are not from the same worlds but they come to an understudying, they come to a truce to fight a common foe (a monster) and at the end Riordan seems to be setting up what could be a very interesting and entertaining coming together of the Carter Kane and Percy Jackson worlds.
