Considering that a lot of classic fantasy genre tropes come from this period and region of history, perhaps that is a bit of an oversight on my part, one that reading Iggulden's Wars of the Roses series has helped me address. In fact, reading these books, combined with some thinking I've been doing recently about plotting, has led me to some interesting reflections. So while this is still a review of the series, I also want to talk a little about those thoughts.
If I were reviewing this is a fantasy book, I would critique is for being repetitive. After all, this is book four in which Lancaster and York fight, kings get captures, kings get killed, people don't have heirs at the appropriate times, and battles are fought over the exact same thing that they were waged a few years ago. However, if this is not a fantasy novel, so I can't blame Iggulden if Ravenspur started to feel repetitive in places. This is, after all, what really happened, or at least the broad strokes are. For some thirty years, the houses of York and Lancaster fought back and forth over the throne of England, and devastated the population in the process.
