This story focuses on a mission of the daVinci back in the Dominion War. Gomez, Lense and Faulwell weren't yet on board, Stevens and P8 Blue were just transferred onto the ship.
And quite honestly, as much as the first part of "War Stories" appealed to me because it granted insight into the characters (aside from showing them as brilliant geniuses), this part falls short in the characterization part. What we get are wisecracks, ideas pulled out of their a**es, in short, business as usual. It's still an interesting story, but not what I was hoping for when book 1 finally showed some inkling of light at the end of the dark tunnel of technobabble, ingenuity (make no mistake, ingenuity isn't bad, as long as there's some kind of personality to back it up) and smartass remarks.
