I'll just echo what other people have already said. This really is the Lord of the Rings of TrekLit. Superb work Mr Mack (and I loved the T:TSCC reference!
Worlds of Deep Space Nine had Andor's population sitting at about eighty million people, so I only hope that it has suffered significantly fewer dead!
That was one thing I was wondering about reading these books. There seemed to be quite a few appearances of Andorians and their different sexes throughout the trilogy, which left me thinking that this may be because we wouldn't be seeing the Blue-skins quite so much after Destiny!
