A great plot would be Percy having to fight against an ancient evil that is somehow related to the concept of death. Since he is the son of death, he has a unique connection to this evil. He could be the only one who can truly understand its motives and weaknesses, but he also has to overcome his own self - doubt and the fear of his new powers.
One interesting plot could be Percy's struggle with his new identity as the son of death. He might have to deal with being feared by others in the demigod community. For example, he could face challenges when trying to form alliances as other demigods are superstitious about his parentage.
Another plot could involve Percy exploring the powers that come with being the son of death. He might discover abilities like being able to communicate with the dead in a more profound way than before. Maybe he can even travel to the underworld more freely and has to face the consequences of interfering with the natural order there.
