The free sample of my book on Amazon ends at a soft point, before the plot starts to take off. I suppose I could cut back on some background/motivational material but I think it helps readers pull for my heroine when things do get sticky. I really don't mind if people keep on reading; the more they read, the more invested they become in the story. Does anyone know if it's possible to increase the sample size on Amazon? I did it on Smashwords, and it was easy.
