Thief of Time

This story is good in parts. It features Susan Sto Helit, my favourite Discworld character; in fact, this is the last we ever see of her (alas). We also get the History Monks and Lu-Tze, who follows the Way of Mrs Cosmopilite. There's an Igor who's quite amusing.

However, the Fifth Horseman of the Apocalyse seems like an idea that needs more work; the abbot reincarnated as a baby is rather tiresome; the mad clockmaker lacks appeal; and the story is infested with Auditors. I'm not keen on the Auditors; I don't think they're well suited to the Discworld; and I frankly wish that Pratchett hadn't invented them.

Furthermore, this is one of those books in which Pratchett goes all cosmic on us, and I think he's better when he keeps his feet on the ground. To put it another way, the story is too weird for its own good.

I quite enjoy it overall, it's quite exciting, and of course there are some funny moments; but it's not one of his best.
