The Zeus Constant is a novel by Callisto Khan, and is a retelling of The Hades Calculus from Zeus's perspective.

Blurb

Zeus, King of Thunder has everything.

A glittering palace, the adoration of her people, and a plan to finally break the stalemate in Elysium's endless war with the colossi. A holy cyborg, inhuman and replicable, to pilot the Gods' eidolons. A pilot worthy of all of the cruelty it took to make her.

On the day her crowning achievement is set to be announced, everything goes wrong. Persephone, her promised pilot, escapes captivity and oaths herself to Zeus's estranged and enigmatic sister, Hades, Lord of the Machine Dead.

Zeus's perfect city cracks under the weight of this political drama. Will its King crack, too? After all, Zeus has everything — to lose.[1]
