What happened on Open Secrets
, IIRC, was that it was originally supposed to be by both authors, and they outlined it together, but Kevin had to bow out due to other things going on in his life and didn't think he deserved full cover credit, so he just got a "Story by" credit inside.
I don't know what the situation is on That Which Divides
, though. (And to vegaslover62
, could it be that the title reminds you of the TOS episode "That Which Survives"?)
