Perhaps the most interesting facet of the writing of Iggulden's Wars of the Roses historical fiction series is how, while the POV character switches frequently within each book, each novel seems to focus on a different character for its primary storyline, the character with whom the reader is meant to sympathize. In the first book, it was Margaret of Anjou. In the second book, it transitioned to York, particularly King Edward. With the third book, the series began to transition its focus to Earl Warwick, Richard Neville.
As I was reading this book, I was wrestling with a confusion that had nothing to do with its contents, and which I should seek to clarify. This book, sold in the US as Margaret of Anjou, is the same book as Trinity, the title under which it is sold in the UK. And now that we have that exceedingly minor point of confusion cleared up, we can get on with the rest of the review.
What is the modern fantasy genre may arguably be said to have been derived from historical fiction. After all, much of classical fantasy was derived from the myths and legends of times gone by, and for a long time (arguably to this day), fantasy was significantly stuck in twelfth century Europe. The genre has since expanded far beyond those historical beginnings, with subgenres like alternative world fantasy that are set in completely different universes, with their own laws of physics, and with characters that sometimes aren't human at all. However, given that heritage, it perhaps should not be terribly surprising that a historical fiction novel about the Wars of the Roses would read more like fantasy than anything else.
Honestly, I'm not even quite sure where to begin reviewing this book (it probably doesn't help that I started reading this series years ago, long before I started consistently reviewing books on this website). I will do a full series review after reviewing Checkmate, but let's focus for now on The Ringed Castle. To put it in as few of words as possible, I loved everything about this book, and not just because my fiancee bought the series for me. It's sort of like what would happen if you took a highly educated Jack Sparrow, and plopped him into the middle of Lord of the Rings level writing, and set the entire thing to the beat of 16th century Russia, but that doesn't even begin to do it justice.
