Melanie has asked me to post the following, received from her via email.
Yes, I will write Captal’s Tower. I’m very sorry it’s taken so long. My sincere thanks to all of you who have been so patient. I’m currently writing the fifth book in the “Glass Thorns” series, and after that my plan is to get to work on Captal’s Tower. If anything about that plan changes, I’ll post on my website (www.melanierawn.com).
