Vellum was the most tedious book I have ever finished. Having read some very positive reviews, I continued on, constant in the hope it would amaze me. That never happened and I'm truly sorry I didn't put it aside after a hundred pages. Frankly, one would have to be much more pretentious than I am to enjoy this book. It's non-linear, buckshot writing that demands far too much of the reader without a valid return. If you want something overblown to bolster your literary ego, maybe this is for you. Those seeking an entertaining, thought-provoking story should look elsewhere.
