I think it'll be Annabeth, Nico, and Reyna. Annabeth because the book is called "Mark of Athena" and because she might be the seventh member. Nico because he obviously knows more then anyone else. Reyna because we need input of what's happening at Camp Jupiter. At least if it's these three Riordan will break the 2 guys 1 girl trios he so loves.
