Identification book on scorpionfish

Hi;

I'm searching for a definitive (if there is one) reference photo identification book that covers the scorpion fishes.

There are several texts covering the nudibranchs and general fish ID books, However, the scorpion fish coverage is small.

Anyone have any ideas?

Thanks, Iain

Im with you on this Iain, so hard to ID them. Maybe ask in the Critter ID forum instead though.
