I seldom quit reading a book before I finish it, but for Relentless I made an exception. I read about a third of the way through the book, and could still make no sense of the plot. I also found the book needlessly violent and confusing. It was supposedly a Christian book, yet I could find no reference to anything remotely Christian. Don't waste your time or money.
Loved it! The suspense kept me on the edge of my seat! Will definitely read the rest of the trilogy, I just have to know what happens next. The only flaw.....the last few pages were not correcty centered so I had to hold it in order to read the words on the left side of the page. Other than that.....great!
