I think I might not review this one.

Philip K. Dick’s last wife has reworked the novel he was working on when he died in 1982 and is publishing the book herself, The Guardian reported. Tessa Dick, the fifth wife of the science-fiction legend, told Self-Publishing Review, an online magazine (selfpublishingreview.com), that her version of “The Owl in Daylight” seeks to express “the spirit” of the proposed book, about which little is known.

There's no reason why this sort of thing—author's last books, being reworked and finished—has to happen. There has never been a good one.
