*Book 4 of PJF* Percy Jackson, now an orphan and owner of Stark Industries, become the second Avenger along with his friends Drew Tanaka and Yuugi Mutou but how will the Yu-Gi-Oh(King of Games) the Chāmusupīchi no ōjo (Princess of Charmspeech) and the Purinsuobuāto(Prince of Arts) deal with a Norse god saving Egypt and still have time to face PTSD? I don't own Percy Jackson and the Olympians The Kane Chronicles, the Avengers or Yu-Gi-Oh! Rick Riordan, Marvel and Takahasi Kazuki
