Yeah, I'm sure Vanguard would make a great TV series, and it's cool that people are so enthusiastic about it, but a bit of a reality check here: With the possible exception of one or two Doctor Who novels, which were written by people who eventually ended up working on the actual TV show, tie-in novels never
get adapted to film. That's just not the way things work.
Sorry to be a party-pooper here, but this is a fairly common misconception. If I had a dime for every time a well-meaning neighbor or relative has asked me when my new Trek or CSI book was going to show up on their TV . . . .
