Tor has cancelled the Spellbinder trilogy's final volume due to poor sales. Rawn was 1/4 of the way through writing the final book but has now abandoned it and started work on a new trilogy, Glass Thorns, with Book 1 planned for 2012.

Some of Rawn's fans (i.e. all of them) have noticed that this new project is very definitely not The Capital's Tower (the 10-years-late-and-counting conclusion to her Exiles trilogy), which Rawn had indicated (although apparently not outright guaranteed) would be her next project post-Spellbinder and The Diviner, a semi-standalone follow-up to The Golden Key. So when Glass Thorns starts, Rawn will have two incomplete trilogies behind her just as she is starting on a third.

Regardless of the reasons for this decision, this cannot be a wise move. Rawn was never a massive-selling author in the first place, and at-best midlisters are much more vulnerable to public opinion and reputation issues than bestsellers (who are more or less bullet-proof). Rawn is, rightly or wrongly, now known the author who can't finish trilogies before moving onto the next project, which cannot bode well for sales of her new series.
