I’ve participated in a few
multi-author series.
Some do well,
with many authors participating.
(The more authors participating,
the better the series does
as there are more authors
to cross-promote.)
Some don’t do well,
with no interest from authors.
What is the main difference?
Whether or not
the series lead author
starts the conversation
with a list of possible plots.
Do the final plots look anything
like these idea starters?
No.
But they get the creativity flowing.
If possible,
start a brainstorming session
with some ideas.
The crazier and wilder the ideas,
the better.
