This was a whirlwind of a book. It almost felt like... well-written fanfiction? I dunno. 
 Things I liked: 
 -The main characters (mostly) 
 -The action and adventure 
 -The Time-Traveling bit 
 -Claire is actually a cool main character, TBH. She's loud and opinionated and she's a skilled doctor, and she's strong and feisty. But she also has emotions and weaknesses and she's just a cool blend of both. 
 -The historical parts. Daily life in a castle, traveling by horseback, the Scottish accents and culture, etc. Those parts were all very well done. 
 Things I disliked: 
 -The writing was sometimes overkill. I found myself skimming paragraphs a couple times per chapter. Maybe it's just because I'm used to reading YA instead of Adult, but there were definitely places the writing could be trimmed. 
 -Parts of the plot. It wandered a bit. The story was never exactly boring, but there were definitely times I was like "where is this going?" 
 -There were a handful of "adult scenes" that I had to skip through. Which obviously I wished weren't included. 
 -Towards the end of the book, there's a quite traumatic incident that happens. 
 -While the two main characters are pretty well-developed, the rest of the characters aren't as much. I could have used another good female character that Claire becomes friends with. 
 I THOUGHT IT WAS GONNA BE A COOL SCOTTISH TIME-TRAVEL BOOK. BUT NOPE. IT'S A ROMANCE BOOK. *sigh* 
 This is a very rambly review. Essentially, I really enjoyed parts of it, and had issues with other parts of it. As such, I don't think I'll read the rest of the series.
