If you think keeping up with all the families and characters is difficult with the show...definitely don't read the book. In book two...I would say in the neighborhood of a third of it was a description of all the families, their sigils, and the ancestry of them. It was crazy! I think you will enjoy the rest of the series (except the final ...maybe the final two...but maybe that's just me).We are finally getting ‘round to binge watching GOT! Just finishing season 3. Too many storylines and families and names to keep track of! Actually to the point of diminishing my enjoyment a bit. I did enjoy the poor bloke who got unwillingly ‘modified’ kinda saw that coming..
