Query: Dont' waste time or money with this unrelentingly dull...

Don't waste your time or money like I did on this unrelentingly dull and disappointing novel! This story was a poorly plotted novel with leaden dialogue and cardboard character development. This story wasn't remotely plausible, and the ending was predictable. Do yourself a favor and skip this one-thank me later!
