As a fan of the show, I walked away very disappointed in this attempt at a tie-in novel. The story itself dragged, and while the author was probably trying to fill a page count quota, it only managed to make the plot seem really uninteresting. Also, there were many instances where it felt like Dean and Sam's roles were mysteriously reversed. Their dialogue read as if they were saying each others lines. Maybe that's up to personal interpretation, but it left me wondering if the writer had even seen an episode of Supernatural before. So a very low score for this one.
