Percy Jackson and the Olympians: Legends

The Isles of the Blest are a group of three paradise islands in the center of Elysium. It is reserved for those who, upon entering the Underworld, are judged and return to Elysium three times in a row after being reborn. They are thought to be the equivalent of islands on the western edge of the Earth, with continuous sunlight. Very few people make it to the Isles, as many prefer eternal residence in the pleasant Elysium to risking rebirth and ending up in Asphodel or the Fields of Punishment at the end of another life. It is believed that the greatest heroes of Greek mythology, such as Achilles, resided there after their deaths.
