I am every so contrite for the delay in responding to your post. I am back, I am at work on the third book in the Dragon Prophecy Trilogy (the title has been changed from "Scourge of Fate" to "Wings of Fate" because after all: dragons), and will be posting the opening chapters on my blog's other site merlinscribe_library. The first chapter is already up.
I apologize for the extremely terrible map in BLADE: I sent Tor a perfectly nice map and that's how they chose to redraw it. To answer your question, CROWN and BLADE take place in the same area, known to the Elves of that time as the Western Reaches and the Western Shore. Kellen knows the Western Shore and Delfiriarathadan Flower Forest as Armethalieh (Daroldan) and Delfier Forest (names change a lot in 12,000 years). I hope this answers your questions and those of your son.
