I've wanted to read the Mary Russell series for a long while, so it's a shame I've started with #10. But I can say with cheerful honesty it's a lovely -- albeit hefty -- way to plunge into the series! I can't say whether the book is formulaic or similar to previous Russell books, but I suspect fans will love this -- a delicious mix of angst, action, and adventure. I'm very eager to start with one and reread this to really appreciate what the characters have endured. I should add that Holmes fans may not enjoy where King has taken the story and the characters but as one not wedded to canon, I enjoyed it.FTC Disclosure: I received this book via GoodReads First Reads giveaway.
