This is the first historical novel I've ever read told as an epistolary novel, and I liked the idea very much because I'm a big fan of the genre (Dracula by Bram Stoker is still one of my favourite book). I found the idea brilliant, and the writing style was very good, flourished and capable to hold the reader's attention till the end. Indeed, it took me just a few days to finish it. I also loved the relationship, more than often overlooked in other historical novels, between Cecily and her sisters, the best part of the novel by far.
What are the issues with it, then? Why 2 stars? Here are my reasons.
1. The protagonist is Cecily Neville, but only apparently. Save, as mentioned, for Cecily's relationship with her sisters Katherine and Anne, she is not really the main charachter, and is not her life that is told. Cecily witnesses the events around her, the political situation, the actions involving her kinsmen, and merely recounts them with a few real intrusions.
2. In a novel about Cecily's life I would've expected a telling of her whole life, if not since her childood, at least since her youth, her first years as Duchess of York, the life in France and then in Dublin, the birth of her children, the beginning of the so called Wars of the Roses. Instead, the novel starts in 1459, at the famous battle of Ludford Bridge, and then goes on into the reign of Edward IV and strangely and abruptly stops when Richard III becomes King. So we are told again of facts widely told in many other novels, while it would have been interesting to read facts prior to this date that usually novels don't take into notice. This is not the tale of Cecily's life, but the tale of the last half of Cecily's life.
3. There are few historical mistakes, that in a so well researched novel really stand out. For example the beginning of the New Year on January 1, when in Medieval times it began on 25 March, Our Lady Day. Or Edward marching into London with "20.000 knights and 30.000 footmen". Considering that in England at the time there was about a total of 1000 knights, and that the population of London was of 40.000, obviously these are fantasy numbers. Not to mention the ever presents George and Edward tall and blonde, and the short and dark Richard. And above all, the fact that Richard claimed the crown using Edward's supposed bastardy as well as that of Edward's children, which comes from the utterly unreliable Thomas More, while all the contemporary sources say otherwise.
4. The treatment of Richard III: this was a bitter finding for me, since I've read another novel by the same author, Virgin Widow, which presented a good Richard, closer to the historical one. Here we find another Richard, more similar to the Tudorish one, ambitious, double faced, cunning, dissembler, greedy for power, who invents the marriage between Edward and Eleanor Talbot, but is ready to brand his mother an adulterer if this doesn't work, who covets the crown at any cost, who unjustly execute Hastings just because he doesn't want to support him and so on. This was really painful to read in a 2020 novel.
