I must say that I'm quite enamored of this series and consider it the best written mystery books I've read in the past, say, five years. Considering that the target audience is pre-teens, I've even gone back to read an adult-level novel and a highly rated YA book to see if I was just mistaken (due to my fanatic delving into fanfiction just a few months prior). But I stand by my opinion. I found the adult writing much too wordy (gotta drum up the word count) and the YA novel dull and cliched.
While most mysteries in the "cozy mystery" camp are mostly filler comprised of the protagonist's every day lives and/or love life, this series has quite interesting historical tidbits. The excellent writing comes from tying those facts in to the mysteries of each book rather than reading like data dumping. Not only that, there are actual mysteries in which you guess the culprit about one chapter ahead of the protagonist. Now that's really saying something. Usually in mysteries, the reader has usually guessed the villain from the second chapter or the villain is a Scooby-doo bad guy--which means they unveil the person at the end, and the audience says a collective, "HUH?" because no one can even remember when that person skulked onto the scene.
This particular one I enjoyed because of the author's own spin on Elizabeth's ill-fated romance with Robert Dudley. Of all the things Queen Elizabeth ever was or accomplished, this is the story that everyone remembers and it is included in every single interpretative fiction piece set in her time period. I must have read about five different variants of the Robert Dudley character in my lifetime--some depicting him as endlessly Machiavellian, some just mindlessly ambitious, some cast him as a horndog. This is the only piece I've come across that depicted him as someone who genuinely loved Elizabeth, and that the reason she couldn't marry him was because of the scandal behind his wife's death. That, although he wasn't the culprit behind it, it had cast such a shadow over his name that the country would never countenance such a match, and that because of it, she was quite broken up about it. I really enjoyed this new interpretation, and the author or authors behind this series are just well-versed in history and writing to make it believable.
Oh, and the protagonist is really delightful. I know most female protagonists in books nowadays claim they're not interested in boys and are only interested in books, etc., but they turn right around and gush over every other male to cross their path. This was a truly believable, non-boy-crazy gal who made it believable. When two other Maids are discussing gowns and dancing and suitors, she's wondering when she can go exercise the Queen's dogs, or being scolded for ruining another kirtle (skirt) with ink spots. This book was especially heart-warming because she really did have a thing for John Hull in this book, but it wasn't so much that she gushed over him, but that she felt embarrassed in his presence and didn't understand why and she would babble in his presence. Sure, I wouldn't have been opposed to seeing a good romance for Lady Grace, but for once, this is a mystery that seems intent on avoiding that pitfall.
In the end, though, it's just good writing, a good, fast-paced plot (although the second in the series was more adventure than mystery) and despite the horrendous summaries attached to these books, I cannot endorse this mystery series enough. I've gone through five of these books in two days, and that's saying something, since I usually don't like reading series. I've read most of the first in the cozy mystery series and given them up because most have just not had the potential to keep me interested.
