I thought this was a marvellous book as close to perfection as a history book can be. I have four reasons for this:
Firstly it was very well written; it read almost like a novel and I was left with a sense of this being a true roller-coaster saga.
Secondly, it was balanced and avoided the opinionated arrogance of so many history books.
Thirdly, it was immensely detailed without a single loose end being untied.
Fourthly, it was the first book on the Wars of the Roses that I have read that covered the entire story from the remotest origins in Richard II's reign to the absolutely last vestiges of Yorkist sympathy in Henry VIII's reign.
Out of 100, I would award this book a decidedly fulsome 97! I deduct three marks: one because nothing can be absolutely perfect, and two because of a series of confusions about Richard III in the penultimate chapter. One was a claim that Richard III was taken to Newark after Bosworth, rather than to Leicester; I assume this was an aberration, or a simple slip of the pen, caused by the fact that some sources say he was buried at The Newarke in Leicester. Another was that initially the author makes mention of the fact that the precise location of the battle of Bosworth was located in 2010, but he later states that the location is not known (my guess is that this was an editing error in a later edition); and a third is that after painting a damning picture of Richard's behaviour and character, the author then spends some time denying the frightful reputation that history has given him (rightly in my humble view).
These are nitpicking points. I enjoyed this book to the full and it is undoubtedly the best, most complete, history of the Wars of the Roses that I have read.
