I have a friend that's a used book dealer. Would you like me to see if he can help?
Yes, if it wouldn't put you to any trouble! I'm more than willing to pay the rates I've seen the books for online, but I can't find a site that I think is reliable and will take a check.
If it wouldn't put you to any trouble, could you inquire about the following books: Castle Kidnapped, Castle Spellbound, and Bride of the Castle, all by John deChancie, as well?
