There were some things I liked about this, the allusions to the first world war and the imagery around that, the ideas about the immutability of Time, the inadvisability of messing with your own time-line, the use of time as a weapon - the time-storms, especially, were terrifyingly executed and excitingly done - The story had tremendous promise but none of it actually went anywhere. Full of loose ends, red herrings and good but not fully thought-through ideas.
As for the clock-face people; I thought there'd be an interesting explanation, an illusion caused by X, leading to Y and a really great conclusion but, no - it was just clock-faced people which is... a bit daft and disappointing.
The quality of the writing and the imagery is the only thing keeping this from a one-star rating. Worth a read, but don't expect too much.
