This may have been my favorite book of the series so far! I love seeing Kendra allow herself to continue to adapt to her new surroundings more as her story continues - I'm torn on whether or not I actually want to see her return to the present day.
The mystery in 'Betrayal in Time' was an engaging one, and it kept me guessing until the end. There were a few points to the mystery that I did figure out as the story went, but if you ask me, that's good writing. Julie McElwain had a clear goal with the mystery here and the plot points followed that goal and supported the ending. When the final twist came about, it didn't feel like it came out of nowhere - Ms. McElwain didn't introduce any convoluted elements just for the sake of tripping up the reader, and I appreciated that a lot.
I know the overall theme of the series is for Kendra to investigate murders, but I'd like to see some mysteries come about that don't actually involve murders. Maybe an extra creepy escape room type of situation, or a masquerade mystery. I'm not sure, and I'll leave that to the author! I'll just continue to read along in the journey.
I was glad to have Rebecca back! Hope to see more of her in future installments, she's a fun character and I hope that Kendra eventually opens up to her. Muldoon was a fun new character, wouldn't mind seeing more of him. And I'm always looking for more Alec and more Duke. It was fun to read more about Alec's past as a spy in the war - I hope we get more of his background.
Also, I know romance is not the central point of the story, but I do have to say, I appreciate the fact that as Kendra and Alec's relationship continues to build, it is portrayed as a healthy relationship. Alec is obviously old fashioned, yet he's open-minded. He's protective but recognizes that he can't stop Kendra from being Kendra, and he doesn't even want to. Kendra may give him a heart attack eventually, but he is getting to know her and he accepts her. In the first book I thought their relationship kind of appeared out of nowhere, but that was the initial attraction, and the foundation for a strong relationship has followed.
Bring on book 5!
SPOILERS/THEORIES BELOW
While reading the third book I started really thinking that there is something linking Kendra to this time period, that her going back in time to this specific time period wasn't at all random. The fact that her mother is a quantum physicist feels very pointed to me, as is the fact that the Duke, a man of science/philosophy, lost his daughter when she was still a child. I think Eleanor is the duke's missing daughter, and she fell through a wormhole, and she's been studying her whole life to see if she could go back. Maybe it's farfetched/too science fiction, but that's my current theory.
