Wow, that is a big gap between the second and third sequel. I wonder what prompted him to write the third after so long. I have done a Google on him and found a bit of a bibliography and luckily they have him on Abebooks which is my go-to place for book buying. Treacle Walker is a bit pricey at £10 but they have The Weirdstone of Brisingamen for £2.35 so I’m going to try that as my first dip into the world of Allan Garner. Thanks for the tip.
