Andromeda: Queen of Monsters
For the past ten years Greece has been at war with the Argonauts. A band of demi-gods who think they should rule over the mortals. In the midst of all this, Andromeda seemingly comes back from the dead and becomes ruler of her father's kingdom.
When, in order to make peace, a marriage is proposed, Andromeda has to keep up appearances in order to bring down the Argonauts once and for all.
The war never ended. It just changed stages.
