The 7 gods of Olympian god week would be a parent of one of the 7 half-bloods. So concluding all the information in, the demigod will be a child of Athena/Minerva and since that prophecy in SoN says wisdom's daughter, I believe it will be Annabeth. I think Rick has become too attached to his characters so naturally he would do that.
