Nevada Barr is not a good writer. As I've said in other reviews, sometimes her sentences are so convoluted, so idiomatic - with idioms of her own making, that no one else has ever come across before - that you have to read them three times to understand what her meaning is. She also is not good at varying sentence structure. About a billion times in every book you'll see the same sentence structure back to back to back, which dulls the reading senses and drags the reader into an unpleasant rhythm. Barr needs to take some serious writing classes and have serious teachers point out her flaws. But this isn't the reason for the one star.
The novel runs along parallel tracks; alternating chapters tell Anna Pigeon's story in contemporary times, as Anna, on temporary assignment in a national park close to the Florida Keys, tries to figure out why a boat blew up and who was on it and what they were up to. She then receives a packet of letters from her sister Molly - letters from their great great great aunt Raffia of the Civil War era, who coincidentally was stationed at Fort Jefferson in the same national park where Anna is living, with her husband. The Civil War is over and Raffia's husband is in charge of a regiment of men guarding the prisoners of Fort Jefferson, the most famous of whom is Dr. Samuel Mudd, given life imprisonment for aiding and abetting the assassination of Abraham Lincoln. (Mudd had set John Wilkes Booth's broken leg.)
I usually find historical fiction a hard pill to swallow. I also hate the alternating chapters gimmick. Inevitably you dislike one story line and enjoy the other, which makes half the book dreadful and painstaking. Raffia and her family's story and the story of the tenants of Fort Jefferson bored me utterly. Then, as you can imagine, Anna Pigeon starts to hallucinate the characters she is reading about in the letters. So, as she is wont to do, she runs around at night in complete darkness and is terrified to see a woman in white whom she thinks is Raffia. Needless to say, this is stupid. But this is not why I rated the book one star. There were enough plot elements - just barely - in the contemporary setting to warrant two stars.
Is the one star because Anna Pigeon spends an entire chapter wondering if two old lesbian lighthouse keepers are transgender? She looks for "signs of a vestigial X chromosome." When one lesbian rubs her cheek Anna ponders whether she is "checking for five o'clock shadow." No. Barr is kind of an idiot, so this is not entirely unexpected coming from her. Is the one star because Anna hopes that "Cuban Hispanics had the same cultural love of family and children she'd noticed in Mexican-American women"? No. Again, Barr has a screw loose. This screw often rattles around in her brain and causes her to place the thoughts of the demented in her characters.
The one star is for the unbelievable, stunning, really inexcusable number of typos and errors in the text. Does Barr have an editor? If so that person should have been fired for letting this book go to press. There were dozens of errors. I didn't even bother counting (I sometimes do) because there were so many. Words are spelled differently several pages apart (sergeant, sergent). Apostrophes were in the wrong place. Apostrophes were inserted in words where they didn't belong. Sometimes "were" was spelled "where" and vice versa. Tolkien is spelled Tolkein. We come across the phrase "despite his straightened circumstances" - which of course should be "straitened circumstances." You expect these kinds of typos from self-published crap books. You don't expect it from a major publisher. What's up with that, G.P. Putnam?
