The HBP...we have all made our statements about whom we think it will 
be. I got this theory from another board and want the gruop to think 
on this. 
 Every book title has been the name of a challenge or threat of some 
sort to Harry. It also represents something, or someone totally new. 
Does this mean (HBP) a new challenge or threat to Harry from someone 
we haven't even heard from? Take this ball and run with it.
