4.5 stars 
 I have to start off by saying that I am absolutely crushed that this is a standalone novel! I want SO desperately to spend more time with these characters! I would read book after book featuring Eve and Jake! I know that there is zero chance of this ever happening, but I still think that I should start a petition to have a sequel written. Do you think Karina would succumb to intense peer pressure?? Nah, probably not. I guess I'll just have to settle for building a time machine so I can read it for the first time all over again. 
 So, cowboys. Who would have guessed that I would have enjoyed a story about cowboys?! This isn't strictly western, though. It's historical fiction thrown into Horror. And it. Is. Glorious. My previous experience with Karina proved to me that she could paint a scene, but this was even beyond what I was expecting from her. She proved exactly how versatile she is by being able to recreate 1851 and a trip through the mountains. Throw in a snow storm, an isolated mountain pass, and a new breed of zombies and it's a match made in heaven! 
 This brings me to my favorite part of the setting; the smell. Eve has a second sense, of sorts, being able to feel more of the world around her. The way that Karina describes the smells is amazing! I wish I could give you all quotes to demonstrate what I mean, but this was an ARC and might have been changed before publication. You'll just have to take my word for it. You'll see what I mean. 
 I can't help but notice that this book is classified as romance, as well as horror. If you've read any of The Artist's Trilogy you'll know that Karina can dish out some heat. I'll admit to expecting a higher quantity of sexual content. I was really pleased on how subtle the romance was though! There was a small amount of heat in Donners, but on the large part Karina focused on creeping me the f*ck out. Mission accomplished! I hereby make a promise to horror fans everywhere: the romance takes a backseat to the thrills and chills. 
 To appreciate the full effect, you should read it when you're home alone. Preferably at night. You'll thank me for it later.
