Obey your Heart's Desires
For those who don't know "Serve your Happiness" I would suggest to start there, because this is actually the second part of the story how Bilbo and Thorin find together after being forced into marriage. Well the marriage will occur here, but the forcing was done in the first part.
Had the first part dealt with the Durins and other dwarrows in the Shire, Bilbo is now reaching the Blue Mountains and has to face a new life in the middle of people he can't understand if they speak their native tongue. Who don't know anything about gardening, good food, laziness and sunshine, about everything that makes life worth living for a hobbit.
But he HAS to be here, and he HAS to find a way to ensure the survival of the dwarven kingdom, because Thorin was the price for his help, and he had accepted it by proposing to him. Now he has to make Thorin's sacrifice for his people worth it. And believe me, it will be hard work to turn this ship around. Because honestly, how can a whole kingdom now so little about something so essential as growing food?
