Busy trying to fit in, can the demigods shift the tide, help in the war and protect Harry, Ron and Hermione? Or is Hogwarts too much?

Una historia donde Harry y Percy intercambian lugares sin recordar nada. [Muchas partes de la trama son gracias a la insuperable imaginación de Rick Riordan, {solo igualada tal vez por J.K. Rowling}] Cronológicamente está ubicado después de que cada héroe derrotó a su respetivo villano, ambientalmente es cuando ambos tienen quince años. /Sinopsis completa dentro/

La mayoría de los niños tiene durante su infancia una amplia gama de juguetes con los que divertirse. Harry no era como ellos, hasta que llegó el soldadito de juguete.
