A delightful, (relatively) standalone novel in Terry Pratchett's Discworld series, Small Gods tells the story of a god who finds himself in the body of a one-eyed tortoise, seeking the help of a true believer. It's a quest story, but also one that tells a story of power, humanism and philosophy - all while being laugh out loud funny. Dr Murallitharan Munisamy joins us for this month's book club, and stays on to chat in our Footnotes about other books that also tackle and highlight philosophical matters.
