I am now writing the sixth novel in the series, which as yet has no title — I refer to it as Book Six. I hope to have it finished by summer 2008, and then the publisher needs six months to a year to publish it. I have no control over the timing, unfortunately. Thank you for your support, and I hope you’ll find this book — the last one in the series — worth the wait. Also see this post which goes into more detail about the creative process for book six.
