A forewarning, as some may be confused by this, the first two chapters lead up to the two being separated. Percy has a secret that has been kept from everyone he knows. Harry has kept a secret from Ron and Hermione. They are the same secrets. Harry and Percy are twins. They were separated at 6 years old and haven't seen each other for 10 years. Also, this is after the Titan War and before Percy was kidnapped by a certain goddess. All rights go to Rick Riordan and J.K. Rowling.
