Query: Should have been a quartet...

Seriously, with this as the final volume, I think the Cleric Quintet would have been better as the Cleric Quartet. If you've read the rest of the series (which is excellent) you'll want to read this one just to know how it all wraps up. The series deserved a better ending though, one that wasn't so painful to read.
