One of the Christmas presents that I considered purchasing for Mom was a replacement for her lost copy of I Dare, in the Meisha Merlin hardback edition. ABE Books has a few listed. They range from $45 to ... $795.00. Yes, that's a three digit number.
I just had to drop Sharon Lee a line about that. As I said to her, "Someone is either a big fan of yours, or a big fan of recreational substances."
