See allAs a fan of nonfiction history books just like those Martin used as inspiration, Fire and Blood perfectly matches the experience of learning more details about events whose ending you already know. The book's small failings lie mostly in the lack of characterizarion of its in-universe author and the historical figures he discusses — something that could have easily been done via more opinionated narration and more personal in-universe sources.

A rather dull read that feels less like a mystery you are suppose to solve (or, at the very least, follow along with) than Doyle deliberately coming up with overcomplications (the poison pills, the unknowning accomplice, etc) and hiding information for the sake of it (the content of Holmes' telegrams, the detail about the cab horse). Also, cutting away from the story for a multichapter flashback to justify the killer's motives sure is... A choice.
There is one fact about this book that perfectly encapsulates its scope, its goals and the experience of reading it: in a book about a war started in 1618, the starting point is almost a century earlier. It takes, in fact, a third of the book for us to reach the inciting incident of the war.
If all you are looking for is a simple narrative or summary, that should make it clear you must look elsewhere. But if you want a full analysis of all factors that led to, fed into and were caused by the thirty years war, this is required reading.
