Westeros is coming — to your fingertips.
In honor of the 20th anniversary of A Game of Thrones, the first book in George R. R. Martin’s A Song of Ice and Fire series, Random House has released an enhanced edition exclusively on iBooks,downloadable here for iPhones and iPads. (The publisher previously worked with iBooks to enhance the Harry Potter series.)
So what exactly is an “enhanced edition” of the book? Aside from all-new watercolor covers for each book (see below), the edition will include colorful character and location illustrations, as well as in-depth and interactive character maps at the start of each chapter, which detail where the point-of-view character is, along with surrounding details of castles and lands. Throughout the text, Martin-approved annotations — shown using a small crown icon — also reveal deeper trivia about the world of ice and fire, while audio clips narrated by actor Roy Dotrice help immerse readers in the novel’s most memorable passages. (In one chapter, a White Walker’s attack comes to sonic life.)
