Prince was supposed to be the roughly same length as the other Realms books at the time--100,000 words, according to my contract--but I wrote long and my editor successfully petitioned for me to be allowed extra pages. With the color map at the front, which ran in the first few printings, and the spot illos throughout, this made Prince something of a prestige paperback release in the Realms line. I still had to tighten the end of the story--I wrote really long--but I greatly appreciated having the extra pages.
Glad you enjoyed it!
I liked it as well, think my copy is on the shelf.
Edit just looked and can't find it. Books are a mess though and getting faded from sunlight.
