A Thread of Deception in the Shadows (The Fate Saga: Hades x Persephone) by Azzie drauch

When Persephone went missing hours before when Hades was going to propose to her, Hades immediately believed Alexandros, the tyrant leader of the demigod group Ethenos behind her kidnapping. Who else but the man behind every favored mortal's disappearance for the last four years? He’d already targeted Persephone more than once, but as the Divine Detective Agency begins to investigate the kidnapping of the Goddess of Spring, things aren’t adding up. Magical signatures strong enough to distort security cameras and magic stronger than most demigods have, and Alexandros not being seen since his attack in Athens during the wintertime… Which begged the question, which god kidnapped Persephone, or who had gifted someone a relic strong enough to imitate a god's magic? As more clues are revealed, Hades, with the Goddess of witchcraft, Hecate, tracks down Persephone’s kidnapper and rescues the goddess of spring from her kidnapper's clutches. which reveals how far the seeds of discontent sown by Alexandros have spread, and the King of the Dead will stop at nothing for retribution against the god or gods responsible.
