Yeah, I know, sorry to get your hopes up there, but it looks like fans waiting for the next main installment in the Song of Ice and Fire series (the basis for HBO's Game of Thrones) will have to wait a little longer. In the meantime, though, you can satiate your thirst for bloody fantasy with A Knight of the Seven Kingdoms.
A Knight of the Seven Kingdoms, according to Observation Deck (who broke his story) is a collection of four previously-published novellas that all take place in Westeros. The stories included are The Hedge Knight, The Sworn Sword, The Mystery Knight, and The Princess and the Queen.
The Princess and the Queen will also appear in an upcoming anthology titled Dangerous Women, edited by George R.R. Martin, due to come out this December.
