Myrcella doesn't die in the books

Jaime Lannister never goes to Dorne in the books as mentioned earlier. Although  factions in Dorne are similarly angered at the Lannisters for Oberyn's death and are ready for revenge. In one of the many plots brewing  Myrcella is badly wounded in one of the escapes — when someone tries to kill her, one of her ears is chopped off. Gruesome but definitely no death. But she's still alive in the books and at the close of A Dance With Dragons she is on her way back to King's Landing. 6)The show is revealing much more about the White Walkers George R. R. Martin introduced the Others in the very first chapter of the first book of A Song of Ice and Fire — and has barely shown them again since.The fast-moving skeletons  don't appear in the books at all. The corpses that the Others reanimate have flesh on them and are slow-moving. The white walkers are a race of human-shaped beings who are extremely difficult to kill, possess superhuman powers, and appear to be extremely hostile toward humans. Apparently there's a lot more of them to come.   7) Khaleesi never meets Tyrion  Tyrion hasn't met Dany as yet in the books. He is captured by Mormont and then sails with him to Mereen but is captured by slavers en route. The pair is then sold the a Yunkish Master, who is camped along with the Yunkish Army outside Mereen. Tyrion is forced to perform a mock joust along with another dwarf whom he meets on his way to mereen at the opening of the fighting pits.   And finally.... But it’s really the North we should care about. White Walkers and giants, wildings and crows. And Jon Snow. Jon Snow is dead. Tricked by Olly to go outside where Alliser and others waited under the pretenses of having information about Benjen. Jon is the central figure in these stories. His own story is far from finished. We’ll have to wait and see.
