The Accidental Empress by Allison Pataki (2015), a historical fiction / romance novel, at a librarian book exchange from a fellow archivist who said she got it as a gift but would never read it. Honestly, half of me wishes I had just let this one go, but I started it, I finished it, and now I'm writing about it.
To be fair, I have really enjoyed some historical romance in the past, particularly when it involves royalty, and this story of a scrappy Bavarian duchess turned Empress of the Austro-Hungarian Empire seemed like it could be a good fit. The book itself is pretty predictable and not bad enough to be a fun bad read or good enough to be a fun good read. The life of Elizabeth (known to her admirers as Sisi), however, is fascinating. Take a minute to check out her Wikipedia page. She's got some excellent mother-in-law tension, a doomed romance, a son who died in a crazy murder-suicide pact, a wild beauty routine, an independent life as a traveler, and then was stabbed to death by an Italian anarchist in Geneva who wanted to kill the next royal personage he saw. Plus her life overlapped with the invention of photography so we have tons of kick ass photographs of her and her beloved hair.
This particular book just goes through the first part of Elizabeth's life, through the couple's coronation in Hungary, and Pataki has already published a second book in the Sisi series that delves into more of her interesting life. (And if that name sounds familiar, Allison Pataki is indeed the daughter of George Pataki, former New York governor and ex-Republican potential presidential candidate.)
On the plus side, the descriptions of court life in Vienna and the Hungarian countryside are very well done, and the book has a nice structure that helps to give the story a little bit of a life. I mostly read this one in airports and on airplanes, and it was just about the perfect thing for that kind of reading experience (except when I ended up sitting next to a woman who had THREE royal historical romances in her carry on bag and then wanted to talk to me about how great the historical romance genre is for half of our flight).
