The Staff of Serapis by Rick Riordan

4.0

I like that this story wasn't just the same as the Carter/Percy one just with Annabeth and Sadie. Firstly, they got along straight off rather than being suspicious. Second, they swapped stories right away too, rather than keeping it to themselves. I think Annabeth would have figured it out on her own.
Clearly, in order to take out Setne all four will need to come together and combine Greek and Egyptian powers.
I like that the reason behind the crossover is historical.
