Initially the contribution from GP was inspiring. Lots of promises of big sales just the initial publishing cost and watch them sell hundreds of copies. I received 14 checks for under a dollar. But after time they badgered me wanting more money to make improvements. In 2021 they have called me 48 times always telling me they can sell more books but they needed $5000 more to make improvements. Calls from 8am to 5pm. User's recommendation: Listen carefully to what they say not what you want to hear.
