Sadly familiar with that. For some reason I went straight to fiction, maybe because there are so many fiction writers here. Haven't been on long enough to find or be found by TV/screen co-sufferers.

But maybe you're only talking about scripts, not IP.

Actually yes. Sold rights to first novel, which was made into a Lifetime movie. Ten years later got rights back. Happy to share more.

For a delicious example of the latter check out the audiobook of The Quiet American read by Joseph Porter.
