I thought the 2 chapters were awesome - definitely a good start
I was kind of confused by the "You don't want to take on the Winter Knight in dark places" line though, considering that he didn't *do* much as the Winter Knight after that. Everyone else did, but Harry's contribution was limited to stuffing a magnesium flare into the wound made by Lara. I was thinking maybe blades of ice, lots of them, but ... no.
The other thing I think worth mentioning is that this über monster of the deep is destroyed by mortal weaponry - from a sword, to a flare, eventually to a grenade. The scariest creature of the sea (up until now
was despatched by 4 sort-of-humans. Maybe there's going to be a theme in this book...
