The sixth book of "A Song Of Ice and Fire" of George R.R. Martin, "The Winds of Winter" (TWOW), launches a preview on the "Game of Thrones" Enhance edition on Apple's iBook.

TWOW sneak peek on GOT: Enhance edition is part of the 20th anniversary of "A Song of Ice and Fire" book series, and is said to be fully released around 2017, Deadline reports.

The upcoming sixth book sneak peak has created a buzz to GOT: Enhance Edition followers. The same publication reported that GOT: Enhance Edition has an imaginative design, making every journey of the characters more exciting. It is said that it would give GOT fans a glimpse to know more the stories of the characters, and to provide an easier guide to Westeros and its people.  

During an interview with Entertainment Weekly, Martin even said, "Anything that confuses you, anything you want to know more about, it's right there at your fingertips. It's an amazing next step in the world of books."

"The Winds Of Winter" prelude in the "Game Of Thrones: Enhanced Edition" is reported to be mainly a chapter of Theon Greyjoy.

Although some rumors say that the book would be available on 2016, this would be highly unlikely since it is already on the last quarter of 2016 and it would be difficult to complete the entire book for Martin.

Meanwhile, the sixth book is said to be the longest book of "A Song of Ice and Fire." As per "A Dance of Dragons" book that took 6 years to finish, Martin is predicting the release of "The Winds of Winter" to run within 2017 to 2018.

The first five books will be available in Enhanced Edition in the coming months of 2016.
