I am going to have to get this now, after your glowing report of it, Warped9... you've got me interested.
BTW, do you have a link to where I can order his Captain April-era stories, or the name of them?
I don't know of any Captain April stories. He did write a collection called
Star Trek: Crew which depicts the rise of Number One from "The Cage" from graduating the Academy to getting to the
Enterprise under Pike. It's quite good. You can order it from Amazon same as I did.
Byrne is only interested in the TOS/TMP era (he's said so himself) and he's obviously got a feel for it. His
Star Trek: Romulans - Pawns Of War is also very good and feels right even if I could quibble with some of his ideas in that one. There we get a perspective of the Romulan encounters with the
Enterprise and the Federation from the Romulan perspective.
