This book divides up the sisters into their own sections told entirely from their POV. Unfortunately I found this tedious and longed for a new vantage point. This book is very dry and lacking the fun political intrigue and interesting characters that usually characterize Gregory's books. With her previous works I've been fascinated even when I'm very familiar with what will happen to the characters involved because she has found a way to shed new light and paint a different account. This version, however, is very boring and lackluster. I'd recommend reading a different book if you want to read about the interesting life of the Grey sisters.
This book was hard to begin because I found Jane so insufferable. She is so full of herself and her belief that her piety makes her so much greater than anyone that she is very hard to take. Unfortunately the beginning is an overly long monologue before the book finally starts to pick up with the events that will lead to her coronation and of course her execution. There is very little backstory about her parents but there are subtle hints at her childhood and her parents actions at the tower make very clear where their priorities are. This account is very different from from the ones I've read in the books by Alison Weir and Ella March Chase. I can understand the authors taking divergent views of her personality but it is interesting that there is such different accounts of things I would have thought were well known, for example in this book Guilford is not a mean savage.
If you aren't familiar with this complicated family or need a reminder you may want to look up what happened with the final wife of King Henry, as Katherine Parr and her husband Thomas are mentioned, as well as the rumors regarding him and the future Queen Elizabeth, but there are few details or backstory in this account. I always found it strange from the other books that Jane and Elizabeth weren't closer given their common faith but perhaps this version of Jane with her competitive piety explains that. I was surprised that this version differs so much in her last days with her confessor. I enjoyed the accounts in the other books of his esteem for her.
Moving on to Katherine was a relief from Jane, at least at first. This version of Katherine sees her shortcomings and has her own ambitions but more than anything wants to marry her beloved. Unfortunately I've had a hard time with this book. I carried on with Jane to get to the end and I'd like to get to Mary to see how she is portrayed in this version, I'm already intrigued that she and the Queen's dwarf are not on good terms, but I find Katherine's section too tedious to read for long. I keep putting it down and I do not look forward to plunging through it. For that reason I haven't been able to finish it and cannot recommend it. I received ARC from NetGalley in exchange for an honest review.
