I didn't know if any of the books mentioned Lyanna and her birth, but I was just corrected by someone who knows.

I do find it silly that it's mentioned that Arya and Sansa wouldn't out wit Baelish. The truth is in the books Sansa was in the Vale for a long time and Arya was still training in Bravos. The TV series does expand with the sisters and Little Finger meets his end with a pretty good story that expands nicely past the books. After all the 2 sisters have learned throughout their journeys, it makes complete sense that they would use womanly deception to out play Little Finger. Kind of an irony if you think about it.
