I see your point regarding the epilogue, KRAD
, but the more I think about it, I see that episode 20 is the climax for the one plotline that runs through the novel (i.e. the Typhon Pact). IMO, the actual confrontation should have been the one to end the novel - leaving the reader with a feeling that things have changed for the worse.
The epilogue, while containing the resolution for Pran's arc and resolution of sorts to the other individual threads, ended the novel too "happily" for my taste (again, IMO only), and having the confrontation of chapter 20 moved to the end would've had that ominous feeling I personally think should be in the background of the post-Destiny / "road to Typhon Pact" novels.
Even so, ASD joins other KRAD (and Mack.. and CLB..) novels as the epitome of 'Modern TrekLit". Again - well done, KRAD
