This question has been asked allot. I have come up with that question too. I think i have come up with an answer. It seems very likely to happen. However, i don't think it will. I know the doors of death had been opened but i think Luke will stay dead. He had a heroic death ending the Percy Jackson series and i don't think Rick Riordan will bring him back. His death ended a series and a prophecy, Luke's death is way to important to the Percy Jackson series for him to come back to life. Although i do admit it would be cool I don't think it will happen. Also, there are already 7 half bloods to answer the call; Annabeth, Percy, Hazel, Frank , Jason, piper, and Leo. Luke would not turn evil because at the end of The Last Olympian he turns good right before he dies. There for i believe Luke will stay dead.
Yes, Luke appears in "The Mark of Athena" as a ghost when Annabeth is on her quest. He communicates with her, providing insights and guidance.
