Let's start with the good. It's an interesting story, and probably at least partially researched. It's not a horrible book, but it is way overwritten. Our Heroine is just not to be believed. She's a 21st century woman who goes back to the 19th century. All good. Except she's an EMT. And a wonderful sketch artist. Oh, and she can recognize every classical music piece that is played to her. Did I mention she plays the guitar? And she manages to do vascular surgery on a kid injured in the wagon train. And knows karate well enough to kill three men who attack her. And she's a crack shot with handgun and an automatic rifle. And of course she's a champion horse rider. And can quote Shakespeare and other classics, as well as Robbie Burns. And both she and her love interest seem to have infinite funds. He can take a wagon train to San Francisco, then take the first boat to Panama, without worry about finances? He went to San Francisco for a job, and yet he doesn't seem to concern himself with money. And don't forget that in the 1850s they all watch YouTube videos on a particular topic - presumably, she's just happened to load her iPod (solar charger, of course) with the ones they'd need. Blah blah blah. Just a bit too much. This is a time travel novel, so some suspension of disbelief is necessary, but the characters should be credible. The story is fun, but the telling of it just isn't there.
For those concerned about sex scenes, there are several. And they're all unnecessarily detailed. I like a good sex scene as much as the next person, but they need to serve a purpose. Those in this book do not. A simple fade to black would have been sufficient for the purpose. If he entered her as the sun set in a blazing fire in the sky one more time, I think I'd have murdered both of them myself.
If you listen to the audiobook, be prepared to hear composers' names mangled - Haydn pronounced "hay"den instead of "high"den, Wagner pronounced as the actor, Robert, not the composer, Richard. Many other annoying mispronunciations as well, which grate on the listeners' ears. And don't get me started on the various accents. The alleged Scottish burr of two main characters is a disaster! And since when is a Scotsman's oath of "och" pronounced with a "CH" instead of a "k"? As one reviewer said, the narrator doing the Scots accents sounds like she's herding Leprechauns. But the narrator is the least of the problems with this book.
