You're absolutely right. At least I tried and can therefore look into a mirror without being ashamed of myself.Better to have submitted and been rejected, than to have never submitted at all.
I did query a paperback story where a splinter group was blocking a planet’s entry to the federation by means of terror, and Bones fell in love with a young Klingon fugitive called L’vnda. Unfortunately, they
weren’t taking unsolicited manuscripts at that time, and it was shit.
In fact, I actually tried to make my story a paperback story too but they didn't want it, most likely because the events in my story wasn't exactly compatible to "canon".
