House of the Dragon: Book vs. Series
HBO’s House of the Dragon is adapted from sections of George R. R. Martin’s 2018 book Fire & Blood. It follows the Targaryen family as a dispute over succession pushes the realm toward civil war.
From Books Adapted
Which books each season covers
House of the Dragon takes several seasons from one history book
House of the Dragon adapts part of Fire & Blood. Its subject is the Dance of the Dragons and the events leading to it. The book covers a much longer stretch of Targaryen history.
| Season | Book and coverage |
|---|---|
| 1 | Fire & Blood: the succession disputes and family history leading into the Dance of the Dragons. |
| 2 | Fire & Blood: the opening stages of the civil war. |
| 3 | Fire & Blood: continues the civil war, including the Battle of the Gullet and the season finale at Tumbleton. |
| 4* | Planned final season continuing the Dance of the Dragons. A precise final book boundary has not been announced. |
| A guide, not an exact match: shows move scenes and storylines between books and seasons. | |
* As of October 18, 2026, season 4 is announced for 2028 and has not aired.
The Dance's conclusion remains ahead of the series. Earlier reigns and other parts of Fire & Blood are not covered in full by these seasons. This is a prequel drawn from a separate book, not the next part of A Song of Ice and Fire.
The original series overtakes the published books
Game of Thrones begins with seasons that mainly follow the first two books. After that, the series splits books across seasons and combines stories that happen at the same time.
| Season | Books and coverage |
|---|---|
| 1 | A Game of Thrones (book 1). |
| 2 | Mainly A Clash of Kings (book 2), with some material brought forward from A Storm of Swords. |
| 3 | Roughly the first half of A Storm of Swords (book 3), with some stories moving at different speeds. |
| 4 | Mainly the later parts of A Storm of Swords, alongside material from A Feast for Crows (book 4) and A Dance with Dragons (book 5). |
| 5 | Combines A Feast for Crows and A Dance with Dragons, with substantial changes and some remaining material from A Storm of Swords. |
| 6 | Uses remaining material from books 4 and 5 while moving beyond them, drawing on Martin's plans and the television writers' own stories. |
| 7 | Continues beyond the published books, using Martin's outline and the television writers' own developments. |
| 8 | Concludes the television story beyond the published books. It is not an adaptation of a published final book. |
| A guide, not an exact match: shows move scenes and storylines between books and seasons. | |
A Feast for Crows and A Dance with Dragons overlap in time and follow different groups of characters. Their stories cannot be separated neatly into two successive television seasons.
The Winds of Winter and A Dream of Spring remain unpublished. Substantial parts of books 4 and 5 remain unadapted, including stories centered on Arianne Martell and Victarion Greyjoy. Martin has said that some events in his ending will match the series and others will differ.
A Knight of the Seven Kingdoms starts with one of three shorter stories
A Knight of the Seven Kingdoms begins with The Hedge Knight. The book called A Knight of the Seven Kingdoms collects that story with The Sworn Sword and The Mystery Knight, in that order.
| Season | Story adapted |
|---|---|
| 1 | The Hedge Knight, the first Dunk and Egg story. |
| 2* | The Sworn Sword, the second story. |
| A guide, not an exact match: shows move scenes and storylines between books and seasons. | |
* Season 2 is announced for 2027 and has not aired.
The Sworn Sword is the next announced adaptation. The Mystery Knight remains unadapted; Martin has said he hopes to bring it to a later season.
What changed from the book
Contains spoilersTap to show
Alicent and Criston's affair is an addition
Season 2 reveals a sexual relationship between Alicent Hightower and Criston Cole. That relationship is not in Fire & Blood.
Condal said the writers had long intended to explore it. He connected it to Criston's repeated failure to separate his feelings from his duty to protect someone. The series gives the two characters a shared secret alongside their political alliance.
How it was adapted
The book's historians disagree about what happened
Fire & Blood presents itself as a history compiled by Archmaester Gyldayn long after the events. He draws on accounts by other people, including the court jester Mushroom. Those witnesses do not always agree.
The series does not stage each event several times to show all those accounts. Ryan Condal said the writers chose what they thought had happened and dramatized that version. Private conversations and motives that the book leaves uncertain become scenes with a particular explanation.
