How I hadn't heard about this book before now, I have no idea. Now I feel that it is my duty to let others know about it. This was an exciting story about survival in the most extreme circumstances. 
 Grace's father is missing, and presumed dead. But she feels that he's still out there somewhere. It just might take some time to find him in the thousands of acres of wild where he disappeared. Her years of wilderness training couldn't be more useful. 
 My favourite part of this book is the writing style. S.R. Johannes has a unique voice which is carried through her characters. Each one, either hero or villain, is a perfect fit with their surroundings. 
 Each chapter begins with a survival skill, but as the book progresses, the tips become less wilderness safety, and more defensive, giving clues to the direction of the story. There is certainly no lack of suspence. I could feel the puzzle pieces fitting together, each clue leading to the bigger picture. 
 So, help me spread the word! Untraceable is a great read!
