Cassie Maddox is sucked back into undercover work by the freakish coincidence of a murder victim that looks just like her. Most of the book is Cassie impersonating the victim to her housemates. There is lots of interesting characterization of Cassie, the housemates, and the victim.

While "Into the woods" kindof sucker-punched me with the ending, this was less traumatic. The ending of this book is a bit more conventional (even using some police procedural trope, slightly twisted).

You should definitely read "Into the woods first", this book references it quite often. It does switch points of view a bit startlingly compared to the previous book.
