Gone Too Deep by Katie Ruggle is the third book in the Search and Rescue series. The first two books are Hold Your Breath and Fan the Flames, which I do recommend reading first. While each romance does stand up well enough on its own, there is an underlying storyline that makes much more sense if you read the books in order.
In the remote Rocky Mountains, lives depend on the Search & Rescue brotherhood. George Holloway has spent his life alone, exploring the treacherous beauty of the Colorado Rockies. He's the best survival expert Search and Rescue has, which makes him the obvious choice to lead Ellie Price through deadly terrain to find her missing father. There's just one problem, Ellie is everything George is not. She is a city girl, charming, gregarious, delicate, small. And when she looks up at him with those big, dark eyes, he swears he would tear the world apart to keep her safe. With a killer on the loose, he may have no choice. Ellie is determined to find her father no matter the cost. But as she and her gorgeous mountain of a guide fight their way through an unforgiving wilderness, they find themselves in the crosshairs of a dangerous man in search of revenge.
Gone Too Deep takes polar opposites and tosses them together. Ellie is talkative and used to city life. George is a silent mountain of a man, used to doing things his way. When Ellie’s father calls and tells her that he is afraid for his life and heading to a mountain cabin, she decided to go in search for him. George is her guide, and eventually so much more. She is not used to roughing it, but will do anything to help her mentally ill father, and George is a good guy that will do anything for here. Most of the story is told through Ellie’s eyes, we only get a page or so of George’s thoughts. Since he is not exactly talkative it makes connecting to him pretty hard, although he does talk to Ellie more than I expected by the end of the book. I thought the survival part of the story, the contributions the the larger story arch, and the slow burn between George and Ellie are very well done. Not getting into George’s head more is my only real complaint here- I wanted to get a better understanding of him and thought his observations would be both interesting and entertaining.
