I must say that I find it ironic that the first book since the destruction of DS9 reads like it might have been an episode of the series. It was like seeing some old friends again.
(As for Sela, I always wanted to see her find out that her origin wasn't quite what she thought. IE: That Tasha was impregnated involuntarily specifically to produce a Romulan-Human hybrid, sort of Romulus's answer to Spock. No that doesn't happen in the book and I'm only mentioning it because now it won't.)
