The Winds of Winter update

So George RR Martin said to an interview that there is a huge twist that will happen on the Winds of Winter that is not possible to happen in the show because a character is already dead in the show that is still alive in the books.
Possible characters George is hinting to:
1. Myrcella:
According to Maggy the Frog's propechy, "Gold shall be their shrouds, and gold shall be their crowns." In the show, Cersei's two sons did become kings, but not Myrcella. In the books, there is this Dornish plan to wage war against Tommen's rule under the banner of Myrcella. So it's possible for Myrcella to sit on the Iron Throne and be queen for a while.
2. Stannis (the Mannis)
Stannis, although already dead in the show, is still alive in the books. ADWD ended with him readying for war against the Boltons.
3. Osha and Rickon
Osha and Rickon currently settles in Skagos. Ser Davos was supposed to go to him after House Manderly's plea to get Rickon out of there to unseat the Boltons from Winterfell. Maybe Stannis will use Rickon to get the entire North to back him to tip the result of the battle for his winning.
4. Jeyne Westerling
This is a huge deviation from the books: Jeyne, the wife of Robb, didn't go to the Red Wedding and she still have with her Robb's child. Maybe the Lannisters will use her and her child to get Winterfell.
5. Mance Rayder
Mance's survival is a big twist that the showrunners didn't bother to put on the show. He was pretty much still alive in the books for it is not really him that was burned on Castle Black. It was but one of the wildlings that wears Melisandre's necklaces. He is currently in Winterfell in a guise of a musician to rescue "Arya."
6. Ser Barristan Selmy
He's supposed to be one of the POVs for the next book. Maybe he will reveal something about the Targaryen's past.
7. The Bolton Family
One of Old Nan's story is the story of a half-human half-white-walker that lives in the north. There's this huge theory that Roose Bolton is the man in Old Nan's story judging on his appearance: has blue eyes and always looks coldly. Maybe the reason why the Boltons have this culture of skinning people is that they wear them to hide their true form. It fits with another theory on the reason why they really want to have Winterfell: under the crypts is a huge thing (maybe the real Night's King) that will start the winter on Westeros.

'The Lost Hero' Review

This book is trying too hard to say that it is about Roman Mythology, that it is different from the previous series, yet the main gods and goddesses involved are just the same. The chapters are oddly separated; they're most of the time too short. The love story is very conspicuous, and I hate that Riordan didn't even bother to present it in a subtle way.
Everything is too 'in-your-face' like the author thinks his readers are too dumb to understand what he's saying. I think the problem is this: This book is for young adults but the author thinks he's still writing for children. His form of writing didn't change a bit and the choice of words and phrases are too childish, even though he's already targeting a new demographic.
