Really confusing description... but what is this book?

-Its about a girl who's moms a whore and she's fat and later in the book she finds out shes fat because her mom spoiled her with food so that shed be fatter than her and wouldnt be competition or something. Her dad is one of the villigers who sleeps with her mom and he tutors her sometimes, then something happens, i forget I think her mom dies, and all the villigers come and they expect her to be the new whore because her house is suppossed to be for the whore and thats the only way she can stay there, so she leaves and there something about a prince (or a knight or something) and he's like un consious or lost his memory or something and she falls in love with him, but he's engaged to this lady who had an affair and got pregnant with the king and she used to be a whore and now they have to get married because she tricked him into sleeping with her before they got married and and he thinks its his kid, not his dads.



And theres like this pig and a dragon and she falls in love with one of them, or maybe its a pig/dragon, Idk, but it turns human at some point and that girl sleeps with it, and at some point she disquises her self as a man and joins some kind of battle group or army and yeah.... thats all I remember... there were 3 books in the series, and the book I read had all 3 in one.
