I believe it starts with the Queen's fool, The Virgins Lover, The Constant Princess, The Other Boleyn Girl, then The Boleyn Inheritance. She also has the Wideacre three book series not related to the other books previously stated....Wideacre, The Favored Child, and Meridon. There are other books she has written but i haven't arrived there yet. =)
This order is definitely correct! The books however are fine as stand alone since I read the Queen's Fool first. But the books above follow Henry VII's wives in order for the first 3 and his heirs in the last 2!!!
THis is so confusing...I wish that the websites for these books made the sequence more clear. I started with "The Other Boleyn Girl" and jumped to "The Queen's Fool" because I thought it came next. I did notice a gap in time between the two stories and now I know why. Thank you for this. I found Gregory's website not to be too clear on this either.
I don't think the order matters that much, since I've read them all and each one gives enough background that you shouldn't be lost anywhere in the stories. The order in which I read them seemed to make the most sense to me chronologically tho.... "The Constant Princess" about Catherine of Aragon, Henry VIII's 1st wife, next "The Other Bolyen Girl "followed by the "Bolyen Inhertiance "(Ann Boylen & future wives), then moving on to Princess(subsequently Queen) Elizabeth; "The Virgin's Lover, "The Queen's Fool" and finally, most recently published "The Other Queen"( Mary Queen of Scots)
This site not only has her Tudor Novels in chronological order, it has the books for The Cousins' War Series as well. An interesting aspect of this site is that there are books from authors other than Gregory inserted into the list in order to "fill in the blanks" history-wise.
