Once again, Geralt of Rivia (albeit looking distinctly less albino this time around) seems to have found his way onto the wrong book cover. In fact, this is pretty similar to the first book, except this time he's on a boat and the boat has been inundated with water which is on fire. Awesome. This is actually a striking cover image and is far more dynamic than the static cover of the first book, even if it is gratuitously OTT.
I think the Gollancz art department has been watching way too much of this music video recently (the cover seems to have been inspired by the inexplicable boat explosion at 1:51):
(thanks to Myshkin for pointing out the uncanny similarities)
