Daughter of Poseidon Forsakes you

Lorde is eighteen again, and the first thing she does is refuse the betrothal she accepted last time. She goes looking for Helios. Her husband Demos and her handmaiden Chloris had put her over the cliffs of Mount Olympus, and it was only while she was dying that she learned Helios, deposed as sun god, had loved her the whole time and had traded away his divinity to buy her another life. Zeus arranges a forced marriage for her regardless. The two of them work on it together from there. The sun god's staff is one of the things they mean to take back, along with the truth about who put her off the cliff.
