City of the Lost

2016

Casey Duncan is a homicide detective with a secret: when she was in college, she killed a man. She was never caught, but he was the grandson of a mobster and she knows that someday this crime will catch up to her. Casey's best friend, Diana, is on the run from a violent, abusive ex-husband. When Diana's husband finds her, and Casey herself is attacked shortly after, Casey knows it's time for the two of them to disappear again. Diana has heard of a town made for people like her, a town that takes in people on the run who want to shed their old lives. You must apply to live in Rockton and if you're accepted, it means walking away entirely from your old life, and living off the grid in the wilds of Canada: no cell phones, no Internet, no mail, no computers, very little electricity, and no way of getting in or out without the town council's approval. As a murderer, Casey isn't a good candidate, but she has something they want: She's a homicide detective, and Rockton has just had its first real murder. She and Diana are in. However, soon after arriving, Casey realizes that the identity of a murderer isn't the only secret Rockton is hiding—in fact, she starts to wonder if she and Diana might be in even more danger in Rockton than they were in their old lives.

What she didn’t expect is that Rockton comes with its own set of secrets and dangers. Now, in A Darkness Absolute, Casey and her fellow Rockton sheriff’s deputy Will chase a cabin-fevered resident into the woods, where they are stranded in a blizzard. Taking shelter in a cave, they discover a former resident who’s been held captive for over a year.

This Fallen Prey

2018

In This Fallen Prey, the next installment of New York Times bestselling author Kelley Armstrong's thriller series, Casey Duncan is about to face her toughest job as police detective in Rockton yet. When Casey first arrived at the off-the-grid town, an isolated community built as a haven for people running from their pasts, she had no idea what to expect, with no cell phones, no internet, no mail, and no way of getting in or out without the town councils approval. She certainly didn't expect to be the homicide detective on two separate cases or to begin a romantic relationship with her boss. But the very last thing she expected was for the council to drop a dangerous criminal into their midst without a plan to keep him imprisoned and to keep others safe. Of course, Oliver Brady claims he's being set up. But the longer Brady stays in town, the more things start to go wrong. When evidence comes to light that someone inside Rockton might be working as his accomplice, helping him to escape, Casey races to figure out who exactly Brady is and what crimes he's truly responsible for committing. In the next page-turning entry in Kelley Armstrong's gripping series, life in Rockton is about to get even more dangerous.
