Immortal Coil by Jeffrey Lang: The first book mentioned when the question of a good Data novel comes up. Chock full of continuity references not just to TNG but also to TOS, however, drawing a line from Roger Korby to Noonian Soong and establishing a vast Star Trek android saga. A saga that David Mack appears to have penned the next chapter in, recently informing us that his Cold Equations trilogy commemorating TNG's 25th anniversary ties back to Lang's work in a major way. All this combines to making Immortal Coil a key entry in the TrekLit canon, and one that many of us are revisiting right now - with The Persistence of Memory en route - or will be revisiting in the future. The official blurb: And the excerpt: Chapter 8.
