My brother bought me Thud! for my birthday.
Its pretty standard Terry Pratchett, by which I mean its excellent but didn't grab me as much as Going Postal did. Still, it does heavilly feature Commander Vimes, who is my favourite Discworld character by a mile.
My brother is the only person who has the secret of buying books for me. Other people don't dare, as they think there's a fair chance I'll already have it. He however buys me newly released books, as he knows I'm too mean to buy a hardback myself.
I'm now re-reading The Standing Dead by Ricardo Pinto. I'm enjoying the trilogy a lot more the second time round for some reason, but it looks like the 3rd book won't be out for ages yet.
After that, its on to Jonathan Strange and Mr Norell Looking forward to it, since most people here seem to like it.
