This plot is very unique. The book is fast paced and I never put it down for long. While the main plot theme--in the visible world--is farfetched, I could still see it happening.
Theo, attending college in Australia, needed a career shift and moved to Kansas (seriously?) where her brother lived. She used a local diner as her office, and, there, met another author. They strike up a friendship which ends tragically for him and life changing for her.
The sub plots also serve to keep the story moving--including a love interest for Theo; a web-based blog of conspiracy theorists who think people are disappearing and being experimented on; and a family of survivalists.
Years before, one of Theo's favorite authors died. The unique situation behind his death is explained and Theo is caught up in it.
