Query: The only interesting thing about the book is dissolved by the end

It is a mediocre book, at best. The plot lines are not credible. The characters one dimensional. The only thing this book has going for it is an interesting ethical dilemma. And then at the end, there is a plot twist that completely takes the dilemma away. I feel like I was tricked into wasting part of my life on this stupid book. Don't waste your time.
