I am strongly considering making book 1 of my series free. It will be a 5 book series and 4 of the books are out now. The fourth just came out last month. The fifth "should" come out in March. Which makes more sense: Waiting until all 5 books are out and then trying to make book 1 free or should I try to make it free now? If I wait, would you wait until about a month after the fifth book comes out and then do it or do it as soon as the fifth book comes out?
