I have an idea for publishing my latest childrens book. It is quite an undertaking having been in the works for almost 10 years (from concept). The concept is getting so big now that it could take me years to write and illustrate it before publishing. So I had an idea:

Publish the book with just the Prologue that I just completed. I have several 'episodes' written and many illustrations ready.
I plan to publish what I have at a low price, say £0.59 and promise that early subscribers will get updates free of charge. Now, when I add a new episode the price goes up to £1.49, £2.49 etc. but owners of the original can download at no extra cost; a bonus for having faith early on.

Will this work however? Lulu (my publisher) are quoting 30 days before the first episode appears on the ibookstore, but in the past when I have made a revision it has appeared within a day. Also I used to change price on Lulu and it would appear on the ibookstore within a few hours. The last few books I changed price on Lulu are still priced the same on the ibookstore even weeks later.

Am I gonna run into trouble here or is my idea viable? Are you able to re-download a new revision at extra cost?

Many thanks in advance for your help.
