I like Karin Slaughter a lot. HOWEVER, this is the first of her books I have not finished reading. After almost 200 pages, I gave up. The story jumps back and forth between Incidents (past and present). This makes it difficult to follow. So it is not very credible if the whole police force is afraid of one bad villain Because, apparently, he is known as a "cop-killer". I'll read Karin Slaughter again, but Will certainly not miss having not finished "Unseen".
