While certainly an enjoyable read, this book doesn't match up to its two co-written predecessors. It isn't as engaging, doesn't weave in the classic moments from the series as neatly, doesn't ever fully come together, doesn't have the emotional heft it thinks it does, and there are a few reasons for that.
The first is the writing style, so fixated on punchy turns of phrase and over-dramatic verbs - screaming, bansheeing, and many, many more - it actually gets distracting by the end. The second is errors, from a line of dialogue that clearly belongs to the Cat instead being ascribed to Rimmer, to a human character somehow depressing a pistol trigger several inches with one, presumably remarkably long, finger, then managing that again while bracing the gun with both hands; it feels a little careless, like it could have done with another proofing pass. The third is the biggest issue: the characters.
The main cast just aren't as rich or strong as they are in the series, or the prior two books. There are discrepancies from those novels, and inconsistencies in behaviour in this one, most notably Lister see-sawing back and forth between being disturbed by deaths, and not caring much at all. Then there are the three most prominent new characters. One exists purely to set up the finale, one shows initial potential only to remain a plot device for the rest of the story, and Kochanski...
Kochanksi is a missed opportunity. She could have provided a fun new perspective, a new dynamic, and there are hints of that at first, but she never develops a real personality beyond moments here or there. She never evolves beyond being Lister's dream girl. This is particularly felt in a repurposing of a classic scene with her in place of Lister, doing little more than parroting his words and reactions, which undermines it, and her. Frankly, the show did a much better job of Kochanski in series seven and eight, and I suspect that was mostly down to Chloe Annett.
If it seems I'm being harsh, it's because I know Doug Naylor's a better writer than this, and I'm frustrated in knowing how much better this could have been. It's good, but...
