I was working on my story when i thought of the plot possibilities, characters etc.etc, when i thought of how many books a book series should have. I wanted to write 9 books whever i took off with Blue Phoenix and stop my procrastination while using certain skills, and they help quite alot. But im still deciding, i might just go with 6 or something. It all depends i guess, i just don't want the reader to get bored of it. I want too keep the reader hooked, so they can come back wanting after finishing one of them. But, on average, how many books should a decent book series have when it comes to not getting old and stale? I ask alot of questions, but since you guys know about stuff like this alittle more then me. I know the Cirque Du Freak books have 12 installments to it and currently reading the series myself. It's pretty good pacing, Darren Shan is a terrific Author.
