I saw it get recommended on a few threads so added it to an Amazon order out of curiosity. It didn't really sound like something I normally read (Terry Pratchett, Bill Bryson & Agatha Christie are favourites) but I figured I could give to the charity shop if I didn't like it.
I'm halfway through and I LOVE it. DD is 5 months old and housework is suffering because every nap I just try to get through a few more pages.
So thanks to everyone who recommended it.
