I’ve never been a fan of reading, so in order to persuade myself otherwise, I’ve begun to force myself into liking it

In order to get interested into a book, for me, I have to really get into it/be interested in the story.

I’ve ALWAYS been obsessed with the tv series “Game of Thrones”
& now “House of the Dragon”

I’ve thought about reading George RR Martin’s books but don’t know where to start, which book should I read first?
… I don’t know if I should read it in chronological order, or just whichever he published first

If anyone has read his books, could you let me know where I should begin?
