Jane Yolen tells us that “after a twenty year hiatus, I have written the fourth book of the young adult Pit Dragon trilogy. Trilogy only because there were three all those years. Set on Austar IV, once a penal planet for the Federation, this fourth book begins 15 minutes after the last book! It’s called Dragon’s Heart and I am in the final revisions now. Should be out next Fall from Harcourt—if all goes well. Of course nothing ever goes well in publishing.”
The first three books were Dragon’s Blood (published in 1982), Heart’s Blood (1984), and A Sending of Dragons (1987).
