- Reviewed in the United States on January 12, 2017This was an excellent book on several accounts. First, the descriptions of Yellowstone NP were right on point. I've visited/worked in that park, and felt like I was right at home. Second, the main character is the complete and total personification of an actual Law Enforcement Ranger. Third, and most importantly, was the description of the visitors to our parks, and how they just don't seem to "get it" when it comes to their own personal safety. Dealing with dumb people is one of the hardest parts of a Ranger's job. Finally, the history and geologic facts presented were amazing! Even though I've spent innumerable hours in the park, I gained even more knowledge from reading this book.
After all that, the story line was captivating. After reading this book, I immediately bought the next two books as well. They didn't disappoint at all. I highly recommend this series!!
- Reviewed in the United States on November 19, 2012This is the first park thriller I've read. Quite an unusual crime setting. Good pace and exciting to the end. Looking forward to the next Colter thriller. Maybe from a rural area in France?
- Reviewed in the United States on September 1, 2013Takes terrorism out of the normal arena and places it in Yellowstone. Some of the Washington DC background is quite interesting but not sure of its accuracy but it does work to explain some of the developments. While not a nail biter I enjoyed the story
- Reviewed in the United States on November 24, 2012Sean Smith's National Park Thriller, Unleashing Coulter's Hell, leads readers outside by going inside our favorite public places including the National Parks and the White House. Spinning faster than a political stump speech, the plot takes Ranger Grayson Cole through his day. His ranger training and personal values champion how he will handle whatever nature and man pack in to a not so typical National Park experience.
This thriller is a must read! It is perfect for a wide range of readers, whether they are armchair nature lovers, seasoned wilderness fanatics, or readers who love suspense and danger, especially when everything is at stake and protecting the public rests on the shoulders of the people we trust. Go outside through this book, Unleashing Coulter's Hell! It also makes a great gift!
- Reviewed in the United States on December 7, 2012Okay, I'm biased because a) I know the author, b) I love the setting (Yellowstone), and c) I love the genre. Unleashing Colter's Hell was enjoyable to read, fast paced but not frantic, and entirely believable given Yellowstone's past and the fanaticism of terrorists. If you buy the ebook also buy the paperback...combined they're still less expensive than most hard copies...so you can prove that you were one of the first to experience a promising new author.
- Reviewed in the United States on February 6, 2013After spending time where this book is written, nice to be back in the park and see what rangers have to do.
- Reviewed in the United States on July 24, 2013I purchased this book because it is set in YNP, an area I enjoy reading about. However, I couldn't finish it. The author is very liberal which is his right. Yet he chooses his novel to preach his viewpoint. Instead of writing a story, the author keeps drifting from the story line to support his personal viewpoint. We all have a viewpoint. However, a good novel shares this subtly, not by seeking to shove it down the reader's throat.
- Reviewed in the United States on November 7, 2012Just finished this book and enjoyed it so much! The author does a great job of setting the scene and made me feel like I was really there. Makes me look at National Parks in a whole new light. Perfect book for anyone who likes intrigue, politics and/or national parks. Can't wait for Sean Smith's next book!
