I've got a copy. It's not worth the price eBay scalpers ask for it, not even close. With all due respect to Ms. Mayhar, it is not a good book. It barely fits into canon (no fault of the author there, canon barely existed when it was written) and the story itself is just a more-implausible rehash of part of The Count of Monte Cristo (which, sorry Ms. Mayhar, is your fault).
If you happen to find a copy at less than $10, go ahead and snag it for your collection. Do not pay more than that.
