Emissary

Of all the recent novelisations I've read recently this one is one of the best. Beyond being a faithful adaptation of the pilot of Deep Space Nine, it actually bothers to give good descriptions and character insights / motivations. My one suggestion is to start with chapter 2. Although the pilot does actually start 3 years in the past with the Borg attack, the first chapter stalls the rest of the story. There is enough referral to the backstory that the first chapter really isn't needed in the book. I dare you future readers to start the book with chapter 2.
