“Detective Casey Duncan and her husband, Sheriff Eric Dalton, are entering a new chapter of life as parents to their six-month-old baby. Their family is hidden away in the sanctuary town of Haven’s Rock where they can live safe and private lives. But when they encounter hikers too close to the borders of Haven’s Rock, they realize they’re in danger of being exposed.

When they find one of the hikers dead the next day, they realize that their paranoia was justified, but they’re no closer to finding out who these people were and what they were doing in the vicinity of Haven’s Rock. Only by tracing the hikers’ movements, as well as examining the recent behavior of their closest neighbors, the workers of a secretive mining camp, will they be able to figure out where the threat is coming from and shut it down. Otherwise, the lives of everyone in Haven’s Rock–and their safe, secure new existence–are at risk.”

Series Info/Source: This is the 4th book in the Haven’s Rock series. I borrowed this on ebook from the library.

Thoughts: I really enjoyed this continuation of the Haven’s Rock series. The mystery is well done, and it was great to see how the new sanctuary town of Haven’t Rock is progressing. I am a big fan of Armstrong and have read the majority of her other series and enjoyed them. I would recommend reading the Rockton series before reading this one because there is quite a bit of background there that ties in with this story. However, this whole series does stand alone fine on its own.

In this book, Casey and Eric are juggling being new parents while ensuring that Haven’s Rock runs smoothly. The autumn is in full swing and they are surprised when they stumble upon a couple of lost hikers. This makes them both a bit paranoid about why the hikers were really out in the middle of the Yukon forest this late in the year. When one of the hikers is found dead the next day, their worry deepens. Exposure is always a danger, and Haven’s Rock has already been dealing with a group of nearby miners, not to mention rumors about possible spies from Rockton.

This story is another wonderful blend of survival elements, combined with a good mysterious police procedural. We get some closure around the mystery of the nearby mining company and also get some insight into what has been happening at Rockton since Casey and Eric left there.

I really enjoyed watching Casey and Eric move onto a new stage of life with their young daughter. Many people seem to want their new baby to be a liability, but instead, they are approaching this new stage of life in a way that brings the people of Haven’s Rock closer together.

This was a quick and easy read that was fast paced, kept you guessing, and well written. I can’t wait to see what the fifth, and final, book of the series holds.

My Summary (5/5): Overall I really enjoyed this book and thought it did a wonderful job of progressing the story. I really enjoyed the police procedural and survival elements to this story. I also enjoyed seeing Casey and Eric enter a new stage of their lives together. I am eager to see what happens in the final book in the series. I would recommend to Rockton fans, or to those who think survival combined with a good murder mystery sounds intriguing.
