Four weeks ago,
Invisible, my second novel,
was number 18
in sales for my publisher.
I then took 3 weeks off,
during which time
I didn’t do any promotion
or fan response.
It sunk to number 43.
A week after I came back
(back to promoting
and back to talking to readers),
Invisible is number 21 on the list.
Promotion works.
Selling works.
Responding to customers (readers) works.
Stop doing all that
and your sales will stop also.
