City of the Lost

This was a fun thriller. I love the central idea (a city in the wilderness where people can disappear to avoid or escape from negative experiences in their life), and Casey is a strong, likable protagonist (which is pretty much par for the course for one of Armstrong's novels). In comparison to Armstrong's other work it's definitely more like Nadia Stafford than the Otherworld material, while still managing to have its own strong sense of identity.
