Query: This book was a disappointment...

While this book was entertaining through the first half, I found that the author seemed to lose sight of where the book was going, how it was going to end, and why it was even written. I was pulled into the story immediately with the crime that the story revolves around. Then, about halfway through the novel I lost interest as nothing was really happening. The ending, which I struggled to get through, was silly and disappointing. I pushed through to the last pages hoping the ending would at least be a bang, but unfortunately it was a barely a whimper. With all the incredible fiction out there, I would not recommend this novel.
