Yep pretty much.

OK I will keep that in mind when reading.

Oh wow you're further than I am t hen. I read the original Olympian books, liked them, but then ended up skipping to the Magnus Chase books because I wasn't sure which order they went in. So now I'm rereading in the right order.

Looks like it's the sixth book in the Olympians series, but you probably need to read the Heroes of Olympus and Trials of Apollo series for this one to make complete sense. This reading order post might help. https://www.beyondthebookends.com/order-of-rick-riordan-books/
