Yeah, I read it when it came out last year - ties up a lot of story threads, but to me not as compelling as the storyline of "One Second After". Worth a read if you read the first, though.
I recently finished three of the four "science of discworld" compendiums and the Tiffany Aching discworld novels from Terry Pratchett, been reading or re-reading some classics - "Treasure Island", "Typee", "Omoo". Halfway through the "World of Ice and Fire" companion to the "Song of Ice and Fire" series to feed my GoT lust.
