While not a novel idea, JCP still executes an interesting cliff-hanger of a book. These are really short glimpses of a story (~600 locations on kindle), so don't expect a full story. I think I'll wait until the stories is complete to continue - I can't do the serialized thing. It certainly looks like it will be a good one though!
Oh - if , like me, you get really annoyed at books that are sold piecemeal just to reap higher profits (ie 10 tiny stories x $2 = 1 $20 sorry) no need to worry here. JCP offers them at 'pay what you want (or think they're worth) on her weppage. Last I checked, they were also free on smashwords.
