This is a long shot!
I searched keywords under Paperbackswap.com and this is what I found:
http://www.paperbackswap.com/book/de...rossroads+Bk+1
I also found the book on Amazon.com
http://www.amazon.com/Spirit-Gate-Cr...der_0765310554
I don't think this is what you were looking for, but thought I'd give it a shot!
Good luck!
