I really think you should try not to mix in Kane chronicles or magnus chase as everything i have read that has done that has been confusing or irrelevant and boring. sticking to the Greek side and I guess Roman is what I feel is best
what is lucy going to be the god of. and anny should be the goddess of forbidden knowledge and gates. forbidden knowledge from her mother and her interactions with Lucy. and gates for the fact she's gatekeeping the Knowledge she's gaining from Lucy
I'm fine with hiatus, though would appreciate a notice like once a month estimating how much longer the wait. Though I havent read Magnus Chase, so I don't know a lot about the Norse in the PJO. Also, Lucian x Zia? Lucian x Sadie?
Tftc!
