'Game of Thrones' author George RR Martin has teased fans by releasing a chapter from his long awaited sixth volume of the 'A Song of Ice and Fire," fantasy series, 'The Winds of Winter.'

The chapter appears on Martin's website and is told from the perspective of Sansa Stark, living under the name Alayne Stone. She is played on the HBO adaptation by Sophie Turner.

Season five of 'Game of Thrones' premieres April 12 on HBO.

Martin has already decided against writing for the sixth season, so he can concentrate on 'The Winds of Winter.'

The previous 'Fire and Ice' book, 'A Dance with Dragons,' came out in 2011.
