This is the dilemma.
I have this book, Ravenmarked. And I have a few fans. And I have a few sequels planned. And the fans would like to see the sequels sometime before they die.
So I work on the sequel, Bloodbonded. And then I finally can’t look at it anymore, so I finish it as much as I can and send it to five beta readers. Two beta readers drop out. Three beta readers haven’t finished the book.
