I got this downloaded to my Kindle at the crack of dawn this morning - and I have just finished it. What can I say? After the rather difficult novel that was 'long earth', Mr P is back on form with this mildly Dickensian (okay, a lot Dickensian!) tale of Dodger, a young sewer 'tosher'. In the best tradition of unlikely heroes everywhere, our lad stumbles on the vicious attck of a young girl, thus plunging headlong into a dark mystery. I'm not going to give away the plot, except to say, that it is pure Pratchett, with twists and turns everywhere, starkly witty social observations and characters that Dickens would wish he had invented. Laugh out loud funny, poignant and waspish, this is a strong contender for my favourite book of the year. My only complaint is that five out of five is not enough. Who knew that sewers could be so interesting?! Recommended!
