Sentinel of Colchis

Helios is dying. His body is fighting off the medical nanites that are meant to keep him alive. That's a problem for Sentinel, the AI who swore to prevent Athenian kings from becoming tyrants. As indifferent as he is to humans, he has to live up to his promise and sees Helios as his answer. His plan? Save the dying prince using abnormal nanites from a hybrid woman, but that's just the first step. King Kronos must die.
