Just got done reading "Typhoon" by Robin White - it's about a thought-to-be-destroyed Russian Typhoon submarine being recommissioned and sold to the Chinese by the Ruskies and the ensuing chase - it's a little bit Crimson Tide/Hunt For Red October but quite enjoyable nonetheless. It reads a bit like early Patrick Robinson, which isn't a bad thing. I'll be grabbing his other books when I can find them.
Night Watch is reserved at the local library for me, thanks NZG
