Larry has read a few media tie-in novels and posted his thoughts here:
Glad Predator came off well, although had hoped someone might comment on the strange-ass alien virus that plays a role therein.
Predator was a renovation of the familiar. If offered an Aliens novel it would be a totally different reading experience as I have some pretty radical ideas in mind. I have wanted to work out a fairly intense space opera in the Aliens universe for some time. (This would then be my last tie-in novel. And I could never do a Star Wars novel–I am in awe of anyone, like Stover, who can handle all that backstory and still move forward.)
