There are plenty of ways to die in the Grand Canyon.

Forensic geologists Cassie Oldfield and Walter Shaws investigate one way: trouble on the canyon's Colorado River. Stranded raft. Life vests unused. Rafters missing.

The only clue to the fate of the rafters is a bag of pebbles caught by the bow line. Following that clue, the geologists uncover a hellish scheme. Not only are the rafters in peril, but the river itself is under attack.

The race to stop it takes Cassie and Walter deep into the canyon, and onto the mighty river, putting their own survival at stake.

► RIVER RUN is the latest adventure in the Forensic Geology Series.

River Run (Forensic Geology #5) Reviews


  • Al

    This is the fifth book of this series and the second that I’ve read. By virtue of the basics of the series you’re going to have some forensic geology involved. That is, after all, the name of the series. But you’re also going to have some unique outdoor settings throughout these books. In this case you’ll get a chance to explore, along with Cassie and Walter, the area of the Grand Canyon with a brief foray into the red rock area of Southern Utah as a bonus. If you’ve visited the Grand Canyon, you’ll be able to imagine what Cassie and Walter are seeing. If you’ve ever taken a ride on a raft down a river, your knuckles will turn white as Walter and Cassie run rapids on the Colorado River in the Grand Canyon. It’s a fun time.

    Oh yeah. I almost forgot. There’s also the mystery at the heart of the story. What happened to the rafters who have gone missing? Figuring that out will keep you on the edge of your seat too. Just be sure to hold on tight and whatever you do, don’t take off your life vest.

    **Originally written for "Books and Pals" book blog. May have received a free review copy. **

    Cassie and Walter are forensic Geologists who have taken a job in the Grand Canyon as a break from there job.

    Cassie and Walter have taken a dream job for Geologists, a documentary on the Grand Canyon. Since they are both forensic geologists this is supposed to be a working vacation for them. But they aren’t on the job one day when they are borrowed by the Search and Rescue to help find where in th canyon raft had been tied up and the crew los? Then the FBI is involved and more people are missing and killed.
    This is an extremely well written book. Having lived in the areas they talk about it captured my attention and didn’t let me go. The people are believable and you get caught up in the story from the first page to the last. Fantastic descriptions of the canyon and rafting. Looking forward to more from this author

  • Brenda Whiteside

    This novel is a tale woven around forensic geologists and the Grand Canyon. I didn’t know there was such a thing as forensic geologists. Rafters are missing and foul play is suspected. Cassie and Walter use pebbles and rocks to follow the clues. If you like really detailed information about rock formations and river flow within the Grand Canyon, you’ll find this story interesting. The geology details overwhelmed the story in my point of view. At times, I didn’t understand why the geologists were even involved. There is a subplot about the river being under attack that seemed forced. But if you enjoy geology with your suspense, you’ll enjoy the book.

    Adventure, Mystery and Drama in the Grand Canyon.

    I really enjoyed this book, could hardly put it down, so many twists and turns in the story that kept you guessing and then guessing again. Beautiful fascinating verbal views of the Canyon, fascinating history, exciting descriptions of river rafting and trying to beat the river and the canyon. The author brought forth the threats to the river while writing a fascinating story to keep my interest. The characters were varying personalities that added that extra color to the story. Read this book, become immersed in it, it is time well spent.

    Great Story . Wonderful Twists and Turns


    Having a Earth Science family, with a geologist, environmental scientist, and a earth science chemist, to name a few, this book " Rocks." Shooting the rapids to find the clues is a good introduction to the rocks and minerals of the Grand Canyon as well a a wild ride down the river. Unfortunately the abuses, by man, of the Colorado are all true . Take some time and pull up Lake Mead on the computer and see how low it is! The other books in this series are recommended as well.

    Love a good mystery

    This is the first time I've had the pleasure of reading a mystery involving forensic geology. I'll have to admit to being skeptical at first but this was an excellent story. The Colorado river is as familiar to me as my own backyard but the geology element in this story makes me want to get back out there and take a deeper look at the geology. The story stands on it's own as an excellent mystery and murder mystery. Looking forward to reading the next book.

    Read: DNF
    Rating: 1,5 Stars

    At 5% read I feel like I cannot really rate this but I'd give it a 1,5, 1 Star for the idea, since that's really awesome, it's the execution that doesn't work for me.
    This feels dryer and harder to get trough than some really freaking wordy scientific texts.
    I so wish this would have been good.

  • Nortxhawk

    Toni Dwiggins’ forensic geology series of books usually give me a thrill ride, but this 5th book in the series just doesn’t do it. I found the plot line needlessly convoluted and hard to follow. The Grand Canyon setting was a superb setting for a wonderful tale for her geologist protagonists but Ms. Dwiggins botched this one by making it a tedious read.

  • Steve Thomas

    The Grand Canyon like you've never seen it

    What an amazing story. Heros and villains play their parts masterfully. The geology of the Grand Canyon along with white water rafting make this a compelling pages turner.

  • Linda

    I have read all five books in the Forensic Geology series, beginning in October 2018. All of them have been dramatic, interesting, and educational. I hope Ms. Dwiggins will be writing more volumes in the future.

    ** HIGHLY RECOMMENDED **

  • Ericka Jade

    I've read the whole series and have loved every one of these books. They are all some type of murder/mystery with a strong female lead character who is a scientist. What's not to love?

  • Karen

    Another good mystery with a geologic theme.

  • Sandra Small

    Excellent!

    Would have never guessed in a million years how this story turned out! Twists and turns and very thrilling! A lot of action too! I didn't want to put it down!

  • linda kellogg

    Unique

    A very different kind of mystery involving the science of geology and the wonders of the Grand Canyon. Exciting and intrigue.

  • T

    2.5 rounded up. I so wanted to like this book more but it just went on and on. Too detailed with a convoluted story.

    I liked Cassie as a narrator and I liked the geology angle.

  • Dawn

    Grand Canyon!!

    Book set in the Grand Canyon!! Can’t beat it! Lots of good rock and river discussions. Good mystery. Thanks for the read.

  • Tim Hart

    Don’t bother. Slow, far fetched, hard to follow and unsatisfying end.
