It's the A to Z Challenge, where I share my favourite book or book series that begins with the day's letter.
Discworld, series, Terry Pratchett
I love, love, love this series. The Discworld series has 40+ books, each one better than the last. Night Watch, pictured, is probably my most enduring favourite, but it really depends on the day and what mood I'm in.
