It helps to have read both series in order to understand the two characters superpowers and the mythological backdrop of who they represent. Egyptian mythology seems to be more complex for my students than Greek mythology and I find readers working toward fluency have an easier time with "Percy Jackson and the Olympians" series than the Kane Chronicles. I'm not sure if that is unique to the school I'm a librarian at or if it is a unique demographic feature. One aspect missing with the giant croc is it doesn't talk. Riordan creates some hysterical gods that take on the characteristics of real myth. I liked the weather god who was slightly insane from trying to predict the unpredictable weather. The croc god is just big and scary with relief from the tension coming from the banter going on in Kane's head and with Percy. If you like Riordan's books, you'll like this short story.
