Two novellas- very different from each other on pace, characterization and world building, common only on the quality of writing.
Diamond dogs is a fast paced thriller about what happens inside an alien artifact that a group of people from Chasm city discover. It deals about how far would you go to feed and fulfill your obsession-an allegory even. Filled with intelligent references and science that we've gotten accustomed to when reading Reynolds, the ending moves the reader and hits you strong.

Turquoise days is a much slower novella dealing with a pattern juggler world, especially about two sisters. Any description more would verge into a spoiler territory, but rest assured that one who reads would love it at the end.
Must read for sci-fi fans though being familiar with Revelation space novels would help.
