Act as an expert on creative writing, outlining, and structuring. I will give a text, analyze it and turn it in the one logical, solid synopsis of the story, sutable for writing a good novel.
Text: 

Crown Princess Rhaenyra Targaryen sails back with her family (husband Daemon, her sons and stepdaughters Baela and Rhaena) to her Dragonstone castle from a royal dinner with her father and Green faction. When they arrive home, Rhaenyra learns from her sons, Jace and Luke, that they have performed a magical ritual to change their appearances in order to avoid rumors about their illegitimacy. Suddenly, Rhaenyra meets her seventeen-year-younger self from the past, Nyra, and her husband’s seventeen-year-younger self, nicknamed Daemion. Nyra and Daemion were accidentally summoned by the magical ritual, done by Luke and Jace. Nyra was summoned while she was returning in the castle at night after her secret sneaking out with her uncle Daemion. They spent a few hours in the city, walked the streets drank in the taverns and ended up in the brothel, where younger Daemon left her after some heavy making out. She was angry at Daemon and frustrated, returned to the castle alone, passed some weird glow and suddenly turned out in the other castle, on the Dragonstone Island, seventeen years in her future. Her sworn guard Criston Cole ran after her in the mist and turned out with her in the future. Nyra meets her future, adult Rhaenyra’s family there.  Nyra meets Rhaenyra, Rhaenyra decides to help her past self to return back.

After a short-heated encounter between Nyra and Daemion in the castle, he stomps away, Nyra follows him to the guest room and seduces Daemion. Next day he asks Rhaenyra for Nyra’s hand in marriage, but Rhaenyra forbids it out of sense of obligation to her children and stepchildren, although she secretly wishes her past self could marry Daemion as that change would provide her with a happy marriage and secure her claim to the throne.
Meanwhile, Baela and Rhaena - the daughters of Daemon from his previous marriage with Laena - fear their existence will be erased if Nyra marries Daemion. They discuss the plan to stop Nyra and Daemion from eloping and enlist Ser Criston to help prevent the marriage of Nyra and Daemion. Jace and Luke also side with Baela and Rhaena against Nyra and Daemion, since Jace is betrothed to Baela and Luke is betrothed to Rhaena.
Later the conflict becomes bigger since Rhaenyra learns that magical ritual literally bounds Jace and Luke’s existence to Nyra and Daemion. In short, either Nyra and Daemion conceive the boys within next several weeks or they will likely stop existing. So, all characters are torn even more. 


In the story there is adult Rhaenyra (34 years old) and Nyra (18 years old).
For Jace and Luke to exist, Nyra and Daemion have to conceive them; but Nyra doesn’t want to be just a broodmare, she wants to marry Daemion; Daemion wants to marry Nyra, Baela and Rhaena want Jace and Luke to be conceived but they also want to prevent Nyra’s marriage. Rhaenyra is ready to do anything to ensure her children exist, but Rhaenyra’s desire for personal happiness and her duty to her current family are at odds with each other; Criston Cole is jealous, secretly hates Daemion, then starts to despise Nyra for sleeping with Daemion. Jace and Luke want Baela and Rhaena to exist, but they also want to get Valyrian appearance by being sired by Daemion and escape the taint of being presumed bastards. Daemon secretly works to help Daemion and Nyra’s relationships and at the same time he searches for the magical way to make Rhaenyra a mother of his daughters instead of Laena.
Baela and Rhaena are twins. Baela is more active and bolder. Rhaena is her sidekick.
