"The Winds of Winter" is the long awaited sixth novel in the fantasy series "A Song of Ice and Fire" by George R.R. Martin. The series has had over 20 POV characters, whose number of chapters across the series ranges from 1 (Arys Oakheart, Melisandre) to 49 (Tyrion Lannister). This market resolves to the name of the character who has the most POV chapters in the next book of the series. If there is a tie, I will resolve to PROB (though this has not happened in any book so far).

I will resolve this market if the book is released (including posthumously). I will not resolve the market on the basis of rumours, leaks, or ambiguous comments by Martin. If it seems likely that the book will never come out (even posthumously), this market will resolve N/A.

For reference, here are the characters with the most chapters in the previous books:

A Game of Thrones:

1. Eddard Stark (15 chapters)

2. Catelyn Stark (11)

3. Daenerys Targaryen (10)

A Clash of Kings:

1. Tyrion Lannister (15 chapters)

2. Arya Stark (10)

3. Jaime Lannister (7)

A Dance with Dragons:

2. Jon Snow (42)

3. Arya Stark (34)
