Rawn began work on the Exiles Trilogy in the early 1990s, releasing The Ruins of Ambrai in 1994 and The Mageborn Traitor in 1997. Rawn's mother, who also served as her first test reader and sounding board for ideas, passed away after this point and Rawn gave up writing for nine years, returning with a new trilogy, Spellbinder, in 2006. The author said she needed a new project to recharge her creative batteries before completing the Exiles Trilogy. However, after Spellbinder and its sequel Fire Raiser were published, the new trilogy was cancelled due to poor sales. Rather than return to the incomplete trilogy, she wrote The Diviner (the long-planned sequel to her 1996 collaborative novel, The Golden Key) and then embarked on a new series, Glass Thorns, a move which irritated many of her fans (not to mention generating substantial commentary on this blog).
Three books have been published in the Glass Thorns sequence: Touchstone, Elsewhens and Thornlost. A fourth volume is completed and due for publication next year, and Rawn is working on a fifth volume. However, she has promised that once that is complete, her next project will indeed be The Captal's Tower. Her statement:
"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."
Good news, following a long period with no news at all (and some ill-advised jabs at fans wondering where the book was in her Spellbinder novels). When The Captal's Tower is released I will finally be able to read the whole trilogy and see what all the fuss is about.
