So, as I understand it, this volume is a sort of introduction to Dee's upcoming Shadows of Avalon series. It was a really fun first look, even better for fans of Arthurian legend. It breaks out of some of the archetypes that have become prevalent in the genre, and while I can understand that some Arthurian fans might take issue with that, I found Dee's little spins very interesting.
A Queen's Tale was a good little love story, set against a backdrop of epic fantasy.
There were some technical errors, the sort of thing one can expect to find in an ebook, but the story more than made up for them.
