The book "Dark in Death" by J.D. Robb has received criticism for being overly lengthy and indulgent in its narrative style. Readers have pointed out that the content could have been more concise, suggesting that the author may have included superfluous details that detract from the overall impact of the story. This perception of bloat can lead to a less engaging reading experience, where the plot suffers due to excessive elaboration.

Moreover, the self-indulgent nature of the writing style may signal that the author prioritizes personal expression over plot development. Fans of the series might expect a more streamlined narrative, focusing on suspense and character development rather than lengthy digressions. As a result, while the premise may be intriguing, the execution may leave some readers feeling unsatisfied with the pacing and presentation of the plot.
