Witches Abroad

I only recently discovered Discworld...how did I go this long without knowing about these books! So glad I fell into the series - they are an absolute delight! Am working my way through the Witches books - this one is number 3... although each book I've read to date can work as a stand-alone - so jump in anywhere, the weather is fine. Here's the guide to reading order: http://www.geeksofdoom.com/GoD/img/2014/04/Discworld-2.21.jpg
As for this one - loved it the most out of the three Witch books I've read to date. Found I was laughing out loud as I was reading. I've now read it and listened to it in the car - good stuff!
