The Sun Will Guide Us Home by Eliana_brekker

Patroclus and Achilles have to join forces with the demigods in order to find their way home when they awaken at the edges of camp half-blood. The Trojan War is still fresh in the minds, despite not knowing how they came to be at the camp. Trust will be tested when a certain god shows up to aid them. It is only through working together that they will be able to return home. Some things will be different, for instance, Percy has never met Achilles. Almost everything, except the plot, belongs to Rick Riordan and Madeline Miller. There are spoilers for the entire Percy Jackson series and Song of Achilles. Canva was used to make the cover.
