I figure reading 5 books will take me a while, but I did read each hunger games book 2 days/book
. Asoiaf is definitely more involved and obviously better quality than a teen series; but, I don't find GRRM's writing frustrating like Tolkien. I think it also helps that I've seen season 1 twice so I've kind of been flying through it. GRRM definitely places greater emphasis on Lyanna in the books than on the show, which leads me to agree with R+L=J.
Assuming I finish all 5 books within the summer months, waiting for book 6 is going to suck. I have no idea why people aren't rioting more that its taken him this long to finish the damn series that he claims to have known the end game since day 1.
