I much preferred the ending on Iron Council to PSS and The Scar, it was somehow more appropriate. Now I'm maybe more used to his style of ending books it wasn't quite as dissapointing, and this was one cliffhanger that felt rather appropriate

Spoils the point of the whole book, maybe, but appropriate

Point: How does the time golem still keep going after Joshua dies? Surely that would get rid of its energy source? And if not, surely its batteries will run out at some point?
