Query: "Insomnia" put me to sleep

This book was an excruciatingly time-consuming, drawn out and mind-numbing waste of time (SK's and mine). For some reason I pushed myself to finish it. Although it did manage to become somewhat more interesting towards the end the book as a whole was not at all something I would expect from an award winning writer. Don't waste your time or patience.
