A lot of Game of Thrones fans are still slightly upset that George RR Martin took time to write a 700-page book of Targaryen history, when he should be spending all waking hours finishing The Winds of Winter.

But, we now know that Fire and Blood does contain important information relating to GoT. And Martin just emphasized again that Fire and Blood is not just a bone he's throwing his fans to get them to leave him alone for a while.

In an exclusive video published on Esquire, Martin said that even Daenerys herself should probably give the book a read to better understand how to play the game of thrones.

"This is a book that Daenerys might actually benefit from reading," Martin said.

Fire and Blood is Martin writing as Archermaester Gyldayn, resident of the citadel in Oldtown, Westeros. And though Daenerys is busy elsewhere getting people to bend the knee, she would really benefit from a reading trip to the citadel.

"She has no access to Archermaester Gyldayn's crumbling manuscripts," Martin told Esquire. "So she's operating on her own there."

But he says that this text holds important information for the Mother of Dragons. "Maybe if she understood a few things more about dragons and her own history in Essos, things would have gone a little differently," he adds.

If we all promise to read Fire and Blood, will you please finish the other one already, George?
