The Death of Time

Chronos is the Keeper of Time, immortal and immobile, his body locked fast to the Heart of Time. His is the duty to ensure that a balance of time is kept, creation, change, adaption and destruction all in due time. But then something starts to poison the flow of the Heart and Chronos has to reach out to the one person he never wanted to face again. The man who bound him to an eternity as a statue sentinel; his son.
But in the modern age, even the god of the underworld has to earn a living, and as the CEO of Charron Shipping Industries, Mr. Hades can't fulfill his debt directly. Instead he calls on mortal descendant, Ananke, who has no clue of her Olympian heritage.
She'd been on a professional mountain search and rescue team, until one day she started to see things that weren't there. She felt like she was slowly losing her mind until many times removed great grandfather Hades himself hunts her down at a cabin and explains the deal to her. Still doubting her sanity, and his, she agrees to be Chronos' eyes, ears and hands until the crisis is averted.
Chronos needs her to be able to blend into the many different pieces of time in vastly different paths of the universe and that means he has to be inside her head almost all the time. It's uncomfortably intimate for both of them, especially when it becomes apparent that Chronos's body is dying along with the Heart of Time.
