The next book due to be released is expected out some time in January. I know that seems so far away now, but it's only 5 weeks or so!
Now, I know most people first discovered Jamie via Insight. And it has been a while since she has released the next book in the series. I'm sorry to tell you the next will not be of Insight, or any series yet she has published. This next book will be a new series within the Web of Hearts story. Don't fret! There is still a LOT more to come from all of Jamie's characters.
Keep on the look out for more information!
