A Goodreads user asked:
is there any percabeth moments? if there arent i wont read it. the only reason i would read it is if percabeth was it in
ThisistheEnd I saw many people say that "We will have to wait until October 6th" I will say that and if Annabeth is in it, she is of course, she might mention Percy. And who knows what could go on! But I say there will (most likely) be Percabeth moments. Check out interviews with Rick Riordan on this book and you may find some things. Good luck!
