I listened to the audiobook which was narrated by Cynthia Farrell.
Let me start by saying that I'm a fan of the Pendergast series written by this duo, so when I saw they were starting a new series with a woman lead, I was intrigued. But ...
Okay, so there's a really fun setup that involves the Donner Party, and if you have yet to read any nonfiction about that, ignore this book and start there. Other than the basic facts, everything here about the Donner Party is fiction - which I was on board with, because who doesn't want to spend time digging around in, and exploring a camp where people practiced cannibalism? But ...
This is my opinion, and not a reflection on you and your potential love of this book, but these guys do not know how to write women characters. At all. To be fair, it's not just the women who were poorly fleshed out, everyone here was rather like cardboard cutouts moving across the high Sierras. The writing is pedestrian, the dialogue simply ridiculous, and the the only reason I finished it was because I'm a glutton for punishment. To be honest, it was really because I read a reviewer say that Pendergast makes a showing - but it was rather late, and more of a cameo, and while I was delighted to see him, how quickly he solved for X annoyed me. Don't worry your pretty heads Ladies, a MAN has arrived!
The pacing throughout is uneven, and the authors seem to spend a lot of time treading water while deciding what to do next. Walking to and from lunch does not a compelling yarn make! Also, we hear the same story several times. Every time a new character needs to be be brought up to speed, we get a full blow by blow recap, over and over again. It felt that the authors were padding things out so they'd meet some minimum page count. If you edited out all the repetitive stuff and moving back and forth, you'd be left with a short story.
But back to these annoying women, both of whom have made appearances in other books by this duo. How are such smart, well educated, and accomplished women so dumb? Oh, and they seem to think that acting as if they were part of a mean girl gang in Middle School is what adults do. OK, so Rachel, the FBI agent is a rookie, but it never occured to her that her boss was assessing her skills? What did she think went on at work? And it goes downhill from there. As for Nora - I don't even have the energy to write about all my issues with her. The premise and backdrop was interesting, but the plot was formulaic and rather predictable, and I was annoyed throughout. I will not be continuing with this series.
